hi guys,
data _null_;
call symput ('dte1', put(today(),yymmn4.));
call symput ('dte2', put(today(),date9.));
run;
data test;
date1=&dte1;
date2=&dte2; run;
the code above wont work/run for date2=&dte2 but it works if date2="&dte2"
Can someone please explaing why?
Thx
Read the log - it's quite helpful 🙂
The generated code turns out to be:
date1=1603;
date2=11Mar2016;
For date1, it's a number so there's no issue.
For date1 however, it appears to be a character so it needs quotes. If you want to keep it as a date then include the d, to specifiy a date literal.
date2="&dte2."d;
The log indicates that it's trying to pass a character variable and points you to the error.

SYMBOLGEN: Macro variable DTE1 resolves to 1603

ohhh right
cuz of the date9. format a character variable is passed to dte2. did not realize that 😞
Thank you Reeza
What would you expect SAS to do if you typed this in a DATA step:
dte2=11Mar2016;
Of course it would generate an error. That's the program you generated, so that's the result that you got.
