Hi,
I have the below call symput statements, when I run for the first time &st_dt. and &en_dt. wont resolve to actual values, but the second run resolves it. Could you please let me know why?
First run has the warnings in the log saying that &dte1 and &dte2 not resolved but second run has no warnings.
data _null_; date1=put(intnx('month',today(),-1,'beginning'),yymmdd10.); call symput('dte1',date1); call symput ('st_dt',"'&dte1.'"); date2=put(intnx('month',today(),-1,'e'), yymmdd10.); call symput('dte2',date2); call symput ('en_dt',"'&dte2.'");
run; %put &dte1.; %put &dte2.; %put &st_dt.; %put &en_dt.;
