Log Path

[Ditza1]

Hi,

Can I get the current path of the log file?

in other word:

proc printto log='c:\em\log1.log';
run;

%let log_path = command to get log path

[Shmuel]

You can change your code to get what you want:

%let log_path =c:\em;
proc printto log="&log_path.\log1.log";
run;

Pay attention - use double quotes instead single quotes.

Some other code set the path or leave it the default value. I am looking
for a way to get it without knowing what happened there

As much as I know, there is no deault path for log.

You use FILENAME staetment to link symbolic name - the fileref - to a path,

or define the path directly in your step - as you have done with PROC PRINTTO in your post.

The PROC PRINTO LOG= defines where to save next sas code lines, until it reaches the:

PROC PRINTTO; RUN; - that closes the saved log file.

If there is a predefined path, it should be in a mcro variabe.

Online session log (window) is held in SAS utility catalog.

I'm not sure you have approach to it.

Just to be more clear, assuming the program is:

<code part 1>
proc printto log=<path and name.log>; run;

<code part 2>

proc pritto; run;

<code part 3>

the saved log will hold only part 2.

I am not sure l used the right terms.

I wrote a macro that can be used in a lot of other macros. The macro
redirect the log to file and needs to redirect it back to where it was at
the end of the macro. So l am looking for a way to get the log path before
I change it, so i can redirect back at the end of the macro

Check the macro-variable SYSPRINTTOLOG and the option LOG, depending on how the sas-session was started one of them is non-missing if the log is already written to a file.

[Ditza1]

This seems really what I was looking for, but I am getting
WARNING: Apparent symbolic reference SYSPRINTTOLOG not resolved.

[Kurt_Bremser]

Use %symexist() first to check if a variable exists; if it exists, inspect its contents.

[Ditza1]

But If It doesn't exist It brings me back to the problem of how to get log path

SYSPRINTTOLOG doesn't  exist in neither of the stages of the following code

%put %symexist(SYSPRINTTOLOG);
filename logfile "Y:\log1.txt";
proc printto log= logfile new ; run;
%put %symexist(SYSPRINTTOLOG);
proc printto;run;
%put %symexist(SYSPRINTTOLOG);

[Kurt_Bremser]

You are right. I tested it in 9.4, both with a workspace server and display manager SAS, and in both cases SYSPRINTTOLOG is never set, although the log is successfully redirected.

This runs contrary to what is written in https://support.sas.com/resources/papers/proceedings15/SAS1575-2015.pdf, and in the relevant parts of the SAS documentation:

Strange. New session started with eg 7.12 on sas 9.4m3. Same result with display manager on the workspace server.

NOTE: PROZEDUR PRINTTO used (Total process time):
      real time           0.00 seconds
      cpu time            0.00 seconds
      

25         
26         %put &=SYSVLONG;
SYSVLONG=9.04.01M3P062415
27         %put &=SYSPRINTTOLOG;
SYSPRINTTOLOG="############\extlog.log"
28         
29         proc printto;run;

This is what you need:

%LET LOG = %SYSFUNC(getoption(LOG));

[Ditza1]

I tried this but I get zero in all LOG macro variables:

filename logfile "C:\log1.txt";
proc printto log= logfile new ; run;
%LET LOG1 = %SYSFUNC(getoption(LOG));
proc printto;run;
%LET LOG2 = %SYSFUNC(getoption(LOG));
%put &LOG0;
%put &LOG1;
%put &LOG2;

[Ditza1]

my version is older then yours

SYSVLONG4=9.04.01M1P12042013

So I guess it works only in the newer versions

( And we have in my company older versions of sas)

Any other Ideas of getting log path without using 

SYSPRINTTOLOG
