Hello everyone,
I will get an error if I run the SAS code below.
Please give me some advise.
Thanks
Mike
%let time1=%sysfunc(time());
%put &time1;
data _null_;
wait=sleep(5);
run;
%let time2=%sysfunc(time());
%put &time2;
%let diff=%eval(&time2-&time1);
*ERROR: A character operand was found in the %EVAL function or %IF condition where a numeric operand is required;
Use SYSEVALF or use a FORMAT with SYSFUNC (second argument) that returns the number of seconds as an integer.
On a related note, if you do switch to %SYSEVALF, understand that the resulting &DIFF will contain a decimal point. That has the potential to cause problems down the road if &DIFF is used in later %EVAL functions.
