This seems like a very simple thing but I just can't seem to get it write.  When using the code below, SAS is truncating the last character wherever variable length is greater than 9.     DATA bins; INPUT binnum bin_desc $ @@; FORMAT bin_desc $10.; DATALINES; 1 [-20,-15) 2 [-5,0) 3 [0,5) 4 [5,10) 5 [10,15) 6 [15,20) 7 [20,25) 8 [25,30) 8 [30,35) 10 [35,40) 11 [40,45) 12 [45,50) 13 [55,60) 14 [60,65) 15 [65,70) 16 [70,75) 17 [75,80) 18 [80,85) 19 [85,90) 20 [90,95) 21 [95,100) 22 [100,HI) ; RUN; ...

Is there a way to output at-risk numbers at specific time points to a file? With the following code, it outputs below the graph and I need to use something like PROC PRINT to view the data.  Also it does not give heading on what the timepoints are.  I need to share this with others and I am not satified with the way it is presented currently.   Here's a sample code- data vagcan; label days ='Days from Exposure to Death' group ='Treatment Group'; input days @@; censored = (days < 0); days = abs(days); if _n_ > 19 then group = 'pretrt1'; else group = 'pretrt2'; datalines; 143 164 188 188 190 192 206 209 213 216 220 227 230 234 246 265 304 -216 -244 142 156 163 198 205 232 232 233 233 233 233 239 240 261 280 280 296 296 323 -204 -344 ; PROC LIFETEST data=vagcan plots=survival(atrisk(outside(0.25))=150 160 180 300); time days*censored(1); strata Group; run; ...

I have a modified (robust) Poisson model and I need to estimate the effect sizes for each combination of two multi-category variables, x1 and x2.  X1 had 28 levels and X2 has 3 levels. Is there an easier, concise way to write the ESTIMATE statement using PROC PLM and some kind of macro? I can keep writing the ESTIMATE statements as below but we will also be collapsing the bins and it is going to be tedious to keep writing it this way.  (I am sorry but I do not have sample data to share).   PROC GENMOD; CLASS x1(ref='0' param=ref) x2 (ref='1' param=ref); MODEL flag=x1 x2 x1*x2/ DIST=POISSON LINK=LOG; REPEATED SUBJECTID=id/type=unstr; ESTIMATE 'X1=1 x2=1' Intercept 1 x1 1 x2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 x1*x2 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0; ESTIMATE 'x1=2 x2=1' Intercept 1 x1 1 x1*x2 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0; ESTIMATE 'x1=3 x2=1' Intercept 1 x1 1 x1*x2 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0; ESTIMATE 'x1=4 x2=1' Intercept 1 x1 1 x1*x2 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0; ESTIMATE 'x1=5 x2=1' Intercept 1 x1 1 x1*x2 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0; ..more statements; RUN; ...

I have to search for set of strings that when used in PRXMATCH comes to more than 262 characters long and SAS gives an unbalanced quotation marks warning.  NOTE: The quoted string currently being processed has become more than 262 characters long. You might have unbalanced quotation marks. The run finishes inspite of the warning and I am wondering if I should break the PRXMATCH into several statements.  A sample code is given below.  The code  runs fine and I am wondering if I should ignore the warning. data _null_; var="24900|24901|24910|24911|24920|24921|24930|24931|24940|24941|24950|24951|24960|24961|24970|24971|24980|24981|24990|24991|25000|25001|25002|25003|25010|25011|25012|25013|25020|25021|25022|25023|25030|25031|25032|25033|25040|25041|25042|25043|25050|25051|25052|25053|25060|25061|25062|25063|25070|25071|25072|25073|25080|25081|25082|25083|25090|25091|25092|25093|36641|V5391|V5867"; varlength=Length(var); %put var; %put varlength; run; ...
