Hello everyone,
Upon learning that sascommunity.org is being decommissioned I decided to move my wiki page to this website as an article to help me continue to share the code. This macro has been around for years and has been constantly evolving to be my pocketknife of survival analysis whether it's graphing or generating tables. I have presented this macro at four separate conferences and have been freely sharing the macro with anyone who is interested.
The research areas of pharmaceuticals and oncology clinical trials greatly depend on time-to-event endpoints such as overall survival and progression-free survival. One of the best graphical displays of these analyses is the Kaplan-Meier curve, which can be simple to generate with the LIFETEST procedure but difficult to customize. Journal articles generally prefer that statistics such as median time-to-event, number of patients, and time-point event-free rate estimates be displayed within the graphic itself, and this was previously difficult to do without an external program such as Microsoft Excel. The macro NEWSURV takes advantage of the Graph Template Language (GTL) that was added with the SG graphics engine to create this level of customizability without the need for backend manipulation. Taking this one step further, the macro was improved to be able to generate a lattice of multiple unique Kaplan-Meier curves for side by side comparisons or condensing figures for publications. The following is a paper describing the functionality of the macro and a description of how the key elements of the macro work.
The original purpose of creating the macro was to make a journal quality Kaplan-Meier (KM) curve that included common survival statistics within the curve itself so that I did not have to manually add them to an image post-hoc. Below is an example using the dataset SASHELP.BMT:
The macro allows for a vast amount of optional customization to fit the user's needs, but also allows for simple macro calls to get the ball rolling.
I added the ability for the macro to take the survival statistics it was calculating and organize them into a clean summary table using the REPORT procedure.
The macro automatically computes many commonly used survival statistics including the following:
There are parameters for customizing the automated analysis, including:
There are multitudes of survival based macros out there in the wild. Why should you choose to try this one instead of one of those or an internal macro?
Nearly all parts of the graph are customizable with multiple options.
The macro was written in SAS 9.2 and most of the options and techniques are still compatible with the older versions (9.2/9.3) of SAS. These features include creating multiple graphs, calculating the concordance index, and running cumulative incidence models.
The beginning of a macro has extensive documentation on each parameter including valid values and how to properly use each one.
Below are the examples that were included in the sascommunity.org webpage.
Make the dataset with the following code (also in macro documentation)

Four Variables:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0);
This is basic macro call using almost only required parameters. The graph is plotted with censor markers and confidence bounds by default, and displays number of patients, number of events, and median time to event within the graph. The following parameters are introduced:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2);
This example shows how to add a CLASS parameter to produce grouped survival curves. Doing so also adds hazard ratios and a p-value to the plot statistical summary table. The example shows how to use other parameters related to the CLASS variable. The following new parameters are introduced:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2, COLOR=black red green, PATTERN=solid, LINESIZE=3pt, SYMBOLSIZE=10pt, XDIVISOR=30.44, XMAX=100, XINCREMENT=10, XLABEL=Months, YTYPE=PPT, YLABEL=Proportion Alive);
This example shows how to change the X and Y axis scale and labels as well as the attributes of the Kaplan-Meier curves. The x-axis is changed from days to months (this does not affect the original dataset) and the tick values are determined by XMAX and XINCREMENT. The y-axis is changed to proportion using the YTYPE parameter. The Kaplan-Meier curves can have their colors, patterns, thickness, and censor symbols modified. The following new parameters are all introduced:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2, COLOR=black red green, PATTERN=solid, LINESIZE=3pt, SYMBOLSIZE=10pt, XDIVISOR=30.44, XMAX=100, XINCREMENT=10, XLABEL=Months, YTYPE=PPT, YLABEL=Proportion Alive, TIMELIST=20 40,TIMEDX=months,DISPLAY=legend timelist);
This example demonstrates changing which statistics are shown within the plot table and how to display Kaplan-Meier time-point event-free rates. One or more event-free rates can be specified, and they will be displayed vertically. The column that shows the time-point can be disabled when displaying only one time-point. The following new parameters are all introduced:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2, COLOR=black red green, PATTERN=solid, LINESIZE=3pt, SYMBOLSIZE=10pt, XDIVISOR=30.44, XMAX=100, XINCREMENT=10, XLABEL=Months, YTYPE=PPT, YLABEL=Proportion Alive, RISKLIST=0 to 100 by 10,RISKLOCATION=BOTTOM,RISKCOLOR=1);
This example gives a basic demonstration of adding the patients-at-risk counts to the bottom of the plot. There are many options to customize the location of the labels, headers, where the table is printed, and even what type of numbers are shown. The following new parameters are all introduced:
Other useful options:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2, COLOR=black red green, PATTERN=solid, LINESIZE=3pt, SYMBOLSIZE=10pt, METHOD=CIF, EV_VL=1);
This example shows how to plot cumulative incidence instead of Kaplan-Meier curves. The following new parameters are all introduced:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2, COLOR=black red green, PATTERN=solid, LINESIZE=3pt, SYMBOLSIZE=10pt, METHOD=KM|CIF, EV_VL=1, SREVERSE=1|0, NMODELS=2, ROWS=2, AUTOALIGN=BOTTOMRIGHT|TOPRIGHT);
This example shows how to produce multiple plots in a lattice diagram. Any options that will be different between plots have the | (capital \) delimiter to designate different settings per option. Any options without a | delimiter will keep the same settings across all models. This example also demonstrates the difference when plotting CIF versus 1-Survival. The following new parameters are all introduced:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2, COLOR=black red green, PATTERN=solid, LINESIZE=3pt, SYMBOLSIZE=10pt, REFLINES=medians,REFLINEAXIS=both);
This example shows how to add reference lines. Reference lines can highlight two different items: medians and time-point estimates. The reference lines can be dropped to either axis. The following new parameters are all introduced:
Other options:
%newsurv(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2, COLOR=black red green, PATTERN=solid, LINESIZE=3pt, SYMBOLSIZE=10pt, PLOTCI=1);
This example shows how to add confidence intervals. Confidence intervals are automatically added for graphs with no CLASS variable. Confidence intervals can be added as a filled background, as lines, or both. By default only a filled background is used similar to the LIFETEST procedure. The following new parameters are all introduced:
Multivariate models are often necessary in survival analysis in order to account for confounding factors. Adjusting for other factors can dramatically change outcomes such as hazard ratio. When outcomes are dramatically changed in a multivariate model it can be inappropriate to plot the unadjusted curves. There are numerous methods available for creating adjusted survival curves, and none are the correct method for all situations. Thus there was a need to have a series of macros that could create the high quality plots of NEWSURV, but with the appropriate methodologies for adjusted survival curves. These macros were designed to adjust survival curves using either the direct adjustment or inverse weights methodologies. A third macro, NEWSURV_DATA, allows the user to pre-calculate their own survival curves and then plot them with the customization of NEWSURV.
The NEWSURV_ADJ_DIRECT macro calculates the adjusted survival curves based off of the predicted survival curves created by the PHREG procedure. This is described in more detail in the PharmaSUG 2017 paper.
The NEWSURV_ADJ_INVWTS macro calculates weights from the LOGISTIC procedure that it then supplies to the LIFETEST procedure WEIGHTS statement.This is described in more detail in the PharmaSUG 2017 paper.
The NEWSURV_DATA macro allows the user to specify their own dataset with time and survival variables that have been previously calculated in order to produce a highly customizable journal quality image. This allows the user to use their own adjustment or calculation method not available in the NEWSURV macros.
%newsurv_adj_invwts(DATA=bmt, TIME=FTIME, CENS=STATUS, CEN_VL=0, SUMMARY=0, CLASS=DIAGNOSIS, CLASSREF=ALL,CLASSORDER=1 3 2, COLOR=black red green,LINESIZE=3pt, SYMBOLSIZE=10pt, CLASSCOV=gender);
This example shows how to make adjusted survival curves using the inverse weights methods. The macro parameters are mainly similar to NEWSURV. The following new parameters are all introduced:
Other options:
Editor's note: we added this mention of SAS-provided macros/options for completeness.
In addition to the thorough options provided here and documented in @JeffMeyers papers, SAS also provides guidance and code for customizing the Kaplan Meier survival plot.
Note that these options/macros work only with the more recent versions of SAS.
This is excellent @JeffMeyers! We know that this article is among the most popular on sasCommunity.org, and we actually had drafted a version of this for you here (as we've done for some others). But your article is so deep and thorough, we had not yet completed the quality-check we felt necessary to publish it. Thank you for managing that for us!
Thank you @ChrisHemedinger. I saw that on the list of unpublished articles so I was hoping there wouldn't be any issues posting this. Let me know if you have any suggestions on the formatting or anything for this article as I'm still new at making these. I'm planning to work on my other big article and potentially new programs to share as well.
This looks really useful, but I cannot download any of the files.
It just says "virus scan in progress...." beneath each file, but nothing more is happening.
Am I doing something wrong?
Hi @ghbg,
Sorry for the inconvenience. There is a bug preventing attachments from working properly. We hope to have this resolved soon.
Best,
Shelley
This is incredibly useful - thank you Jeff for making it available.
I am having difficulty with one small thing: I cannot get the image file to save. I have followed the instructions in the macro, and specified the following:
GPATH=F:\Folder\Folder\Folder\My folder\
PLOTTYPE=png
PLOTNAME=test
But nothing appears in the folder that I specify. Is there another part that I am missing??
works like a dream - thanks very much
Hi, this is a really useful macro!
I was wondering if it is possible to display the number of events alongside the number at risk, rather than the number of cumulative events?
Thanks!
Hi, thank you very much for this helpful macro!
We do have a question concerning the use of the macro.
With every run of the macro (used to plot a Kaplan-Meier-curve) the output window is resetted.
Is it possible to prevent the macro from resseting the output window?
We do have to run Kaplan-Meier (KM) for different outcome variables and it would be very helpful to have all KM curves in one output window.
Thanks!
sasstats
Hello Jeff,
thanks for your answer.
We are using SAS 9.4 on PCs.
Our preferred output destinations are HTML, excel or rtf.
Changing the plot name wouldn't really solve our problem.
Is there any option that enables the macro to append new plots instead of overwriting?
Our aim is to get several different Kaplan-Meier curves (for different groups) in one Excel sheet.
Normally, without using the Macro %newsurv SAS appends every new plot or table to an existing output-window or rtf-File.
But the macro %newsurv overwrites an existing file as you said above.
sasstats
Hello @sasstats,
Could you link the code you're trying to use? Normally when you wrap ODS tags around the macro it'll just append it to the report you have.
Example:
ODS RTF file='test.rtf';
%newsurv(...)
%newsurv(...)
ods rtf close;
However if you have OUTDOC specified in the macro call it will only write to that single file. So if you're trying to append the graph to a report within ODS tags make sure that OUTDOC is blank. Otherwise if you link the code you're trying to use (can use ... for your other report items) I can test it out on our Windows server to see if there's a glitch there as we normally use Linux.
Hello Jeff,
it works fine!
Thank you very much!!!
This is a great help for us!
sasstats
Hello Jeff @JeffMeyers ,
I am getting the error "ERROR: Subquery evaluated to more than one row." when using the %newsurv_adj_direct macro. Even when I use the example data. Do you know why this is happening?
I am using SAS Online studio.
Thanks
Ubai
Can the y-axis be specified for a cumulative incidence curve. I want the maximum to be 30% (0.30).
Hi @JeffMeyers ,
Thanks for this wonderful macro.
I am getting an error when using PARHEADERALIGN:
ERROR: The keyword parameter PARHEADERALIGN was not defined with the macro.
Also, would it be possible to show the strata variable label in the graph?
Thank you
Hello everyone. I've posted a new version of the macro (newsurv_web_042020.sas) that has my most recent updates and also combines the adjusted macros into the original NEWSURV. Now you can specify method=DIRECT or method=INVWTS to do the adjusted methods. Just a note that I don't use Windows SAS so if there are any bugs found while using with Windows please e-mail me at meyers.jeffrey@mayo.edu to get the fastest response.
@Ubai I found that error was because Windows SAS handled missing values differently than Linux SAS. Please try my new version to see if you get the error still (see note in previous paragraph).
@greg_maislin You can set YMAX to be either 30 or 0.3 depending on which option you have set for YTYPE. Example:
%newsurv(data=sashelp.bmt,time=t,cens=status,method=cif,class=group,ev_vl=1,ymax=30)
@Alnajar The option you are looking for is PARALIGN, not PARHEADERALIGN I believe.
@JeffMeyers Hi Jeff and thank you for the update. I really appreciate the effort you put into this macro. I use it all the time for my research.
I've just tried the macro in SAS online studio. I tried adjusting survival curves and the macro works flawlessly. I was wondering, is it possible to adjust CIF curves as well?
Removing the censor marker from the legend was a long waited change.
Also, what method does the macro use when calculating the adjusted HR for an outcome with a competing risk(s)? Can I manipulate the method?
Hello @Ubai. The latest version I posted can remove the censor markers from the legend by setting CENSORMARKERS=2. I honestly do not know if it is possible to adjust CIF curves. I personally am not a statistician but am a statistical programmer. I had Terry Therneau teach me about adjusted survival here but have not had any interactions with adjusted CIF.
The adjusted hazard ratios with competing risks are done withing the PHREG procedure using the EVENTCODE option in the MODELS statement.
@JeffMeyers exactly, I have noticed the addition of censormarkers = 2 and I was complimenting it. 🙂🙂
as far as I know, there are methods to adjusted CIF curves. I found some literature on this topic. The first two articles are about SAS macros that runs this task. I don't think that it's technically so much different than adjusting KM curves.
However, if the CIF is adjustable, it might be more practical to separate split the macro variable METHOD into variable METHOD with values (KM,CIF) as it was before and a new variable for example ADJ_Method (NONE,DIRECT, INVWTS) with default = NONE.

Keep up the good work 😉
Ubai
This is a fantastically useful macro, thank you. I am having one small problem though:
I want to increase the size of the font in my graphic, for the axes, labels and patients-at-risk box. I have found the elements that do this in the instructions (XTICKVALSIZE, LABELSIZE, PARSIZE, etc). The problem is that when I increase the font for the patients-at-risk box above about 10pt, the labels sort of overlap each other and the numbers on each row squash together. Hopefully the picture below shows what I mean. I can't figure out how to space them out. Aside from this, it looks great.
Can anyone help?
Hello @ghbg. Use the parameter RISKROWWEIGHTS to allocate more space to the patients at risk numbers. The number represents how much graph space each row gets as a proportion. Try setting it to 0.045 and increase or decrease from there.
thanks. works perfectly
Hi @JeffMeyers . Sorry to post again but I have another query...
I am using a large dataset with ~26,000 records in one exposure group. I need to make a black and white graph, so I am using the following parameters in the NEWSURV macro:
COLOR=black,
PATTERN= SOLID SHORTDASH,
When I run this, I get an error message saying:
The STEPPLOT is not drawn because the limit for maximum number of observations per patterned line has been exceeded. You can set line pattern to SOLID or set LINEPATTERNOBSMAX=67200 in the ODS GRAPHICS statement to enable the plot. Increasing this limit could make Java VM run out of memory. See product documentation for related considerations.
I don't get this error when I use coloured lines (e.g. black blue). I have tried including LINEPATTERNOBSMAX=67200 in the code, as suggested, but it doesn't recognise this as a parameter.
Could you let me know if there is a way around this?
Hello @ghbg,
That error is not something I generate in the macro but from SAS itself. Basically it is saying that there are too many dashed objects in the dashed line being made I think. There isn't a parameter in my macro for this at the moment I think, but if you search through the macro code for the SGRENDER it runs, find the ODS GRAPHICS that comes just before it you can add that LINEPATTERNOBSMAX into that statement to adjust it on your end.
works a treat. thanks again for the speedy response @JeffMeyers
Hi @JeffMeyers - I'm trying to output the plots in a vector scalable format. I am currently using SAS Enterprise Guide 7.15.
I added:
ODS LISTING;
GPATH = "mypathway..."
PLOTNAME = test1,
SVG = 1,
DESTINATION = PDF
ODS LISTING close;
Yet I dont get anything in my file path. Also, how would I know if the file successfully saved as a vector scalable file? I tried doing a ODS file file and it outputs a pdf file but it is a normal .pdf file (not sure if its vector scalable). Thanks for any help
Hello @bransivs
To output a scalable vector graphic in PDF format you need to use OUTDOC=filepath/filename.pdf. PDF is a document and not an image, but the graphics contained will be scalable vector graph. You will know if it worked by being able to select the text and zoom in without fuzziness. You can also skip this if you want to wrap the macro in your own ODS PDF tags.
Another option is to save as EMF (setting PLOTTYPE=EMF, SVG=1, gpath=wherever). I haven't tested this code in Enterprise guide so I'm not sure if it works the best. You could then insert into an Office product and do right click-> edit to make sure the file is scalable vector. One caveat is that this doesn't work with dashed lines.
Thanks Jeff - following up on the vector formatting^
Is there any other work around? The vector formatting mentioned above does not produce a vector image for it, regardless of what ODS PDF out statement I wrap around the macro
Hi @JeffMeyers
I am having difficulty getting the PAR subtitle to align in the same way as my risk labels in the PAR table...
PARHEADER=Number at risk,
PARALIGN=labels,
RISKLOCATION=bottom,
RISKLABELLOCATION=left
This gives the PAR table outside the plot, with risk labels to the left and PAR subtitle above the risk labels, but the subtitle is left-aligned whereas the risk labels are right-aligned. See image below.
The issue only occurs when I have longer risk labels, as here. Shorter labels seem to automatically left-align, along with the subtitle:
Any idea how I can get "number at risk" right-aligned like the longer risk labels ("donor with/without endocarditis")?
Hello @ghbg. The labels are always right aligned in that space. The reason they look left aligned in your shorter label example is that they're the same length with similar characters. They are still right aligned within their space with the PAR header starting from the left end of their space. The PAR header is created differently from these as it's drawn with annotation so that it can cross different graph spaces without getting cut off, so I can't set it to be right aligned like those labels are. It may be tedious, but the only real way around it would be to add some spaces to the front of the PAR header to bump it more to the right. E.G. PARHEADER=%str( Number at risk). This should work, but if not then you would need to use non-breaking space characters:
data _null_;
call symputx('nbs','A0'x);
run;
PARHEADER=&nbs.&nbs.&nbs.&nbs.Patients at risk
thanks very much. i thought it might need something like that.
can i also ask how i might left-align the risk labels instead? would it just be adding spaces after the shorter label?
@ghbg If you go into your version of the macro you have downloaded you can search in the graph template code for the ROW Headers section that make these. They are created with entry statements within a ROWHEADERS block, and you would just need to change the HALIGN option from RIGHT to LEFT. I don't have an option for it currently as the options are currently trying to remove as much white space from the left side of the plot as possible.
Hi @JeffMeyers
I am having a problem with the title of my graph. The text is not wrapping, just continuing on one line and getting cut off at the edge of the plot. See below.
Can you suggest a solution?
thanks
George
Hello @ghbg, you can use the ` symbol (lowercase ~) to specify a line break in the title/ovtitle options.
@JeffMeyers This macro very useful to me. Thanks. I am having the issue on Y having big label name, How Can I adjust or is there possibility that I can split into two lines, because its bigger than the height of the png set up in macro call.
Dear @JeffMeyers ,
I'm plotting multiple KM curves in one figure. I would like to leave the title for some plots blank. However when I do this the plot expands to the whole area originally planed for a plot without a title. I tried using the ` symbol, but it did not work.
Here is an example of what I am looking for. In this case I used a title and then deleted it manually using a picture editing software.
I also deleted the title for the Y axis. Is there a way to leave it empty? If it do not use a title the default title for the axis is used.
Any ideas?
There are two solutions:
Solution 1: You can adjust the line size of the Y axis label using LSIZE = 12 pt. Try different sizes for you title, 8 or 9 should work.
Solution 2: You can use the ` Symbol in your title to split it into two lines.
@Ubai. Thanks your second solution worked. thanks
Hello @Ubai
there are two things you can try. The first is to set the title to be %str( ) (with a space). This makes a macro space character. The second is to make a non breaking space macro variable and use that.
Data _null_;
call symput('nbs','A0'x);
run;
then use &nbs in the title or label.
Hello @JeffMeyers . Thank you for this amazing macro. I am newly using it. However I have some questions regarding how to control the headers and some other stuff mentioned in the image. Any suggestion in adjusting those. In headers controlling, I was able to do hazard ratio and P value but not the 'GRPVAR', which parameter controls the heading. Thank you. May be I am missing some Parameters in macro call.

Hi Jeff, I was wondering how to change the logrank pvalue display from <.0001 to <0.0001? If that's possible. I tried playing around with pvaldigits parameter but it seemed to make no difference. Thanks very much.
Hi @JeffMeyers
Sorry for another query. This macro is extremely useful and has helped enormously with my publications. Thank you.
I am making a lattice with 4 panels, each with a different KM curve. I need to save it as a png and as a pdf. The pdf looks perfect but the png image quality is very low, despite increasing the DPI. Changing the dpi doesn't seem to affect the png image quality (or the size of the file) at all - it just makes the pdf look quite speckled. I am using the following commands to make the PDF and PNG:
DPI=800,
PLOTNAME=my_graph,
GPATH=C:\my folder,
DESTINATION=pdf,
SVG=1,
OUTDOC=C:\my folder\my_graph.pdf
The pdf is great but I also need to create an image that I can include in a word document, and the PNG is no good. See attached close up
can you help at all?
Hello @ghbg ,
I tested this in my programming environment. I may need to do some code updating, but I found that I needed to turn on ODS LISTING prior to running the macro for the DPI to affect the final PNG image. This also only worked if I removed the outdoc, svg and destination options. I will look into the reasons for this and see if I can make some changes.
Hello @KDS1 ,
The macro makes use of the PVALUE format which doesn't seem to like having the leading zero. I chose to use this format since it was readily available and so that the macro wasn't making a format it would later need to erase. If you have an internal picture format or regular format you would rather use you can search through the macro for the PVALDIGITS keyword in the macro text to replace the format next to it. It should look something like: strip(put(b.pval,pvalue%sysevalf(6.&&pvaldigits&z))) where the macro is applying the number of p-value digits to the PVALUE format.
I am having a problem with the axis colours. They are coming out in black on the png file, but grey on the pdf, even though i have specified axiscolor=black
any suggestions?
Hi @JeffMeyers ,
I am looking for a macro that can handle pre-calculated weights in order to produce a weighted HR and weighted KM (i.e. weighted median and N at risk). The weights are stored in the original dataset as variable sw. In addition, I need to add option COVSANDWICH when estimating the 95%CI. I was wondering, if you have a version of the %NEWSURV macro that can do this.
PROC PHREG DATA=data COVSANDWICH;
weight sw;
CLASS arm (Ref=first);
MODEL OS*CNSR(1)=arm /rl=wald ties=efron;
run;
proc lifetest data=data;
time OS*CNSR(1);
strata arm;
weight sw;
run;
Hi @JeffMeyers
Thanks for all the help on this. Your suggestion for enabling the DPI by adding "ods listing" has worked.
I have another small problem. I don't know if it is in the macro or what I typing:
I cannot get a line break in the PVALHEADER text. If I use the ` delimiters, these just appear in the text, so including "PVALHEADER=` ` ` log rank tesp=" shows exactly this (without any line breaks).
Any advice?
Hello @ghbg
I don't think the pvalheader is really set to have line breaks since it's usually in one row. If you would like to add some line breaks I would suggest adding something to TABLECOMMENTS and then listing tablecomments prior to pval in the DISPLAY option.
Example:
tablecomments=%str( )`%str( )`%str( ), display=...other stuff...tablecomments pval,
