Hello
I want to create a sas macro varaible xx and I get an error.
/*ERROR: Function name missing in %SYSFUNC or %QSYSFUNC macro function reference.*/
/*ERROR: %EVAL function has no expression to evaluate, or %IF statement has no condition.*/
When I create macro var YY I don't get error.
What is the problem with xx?
%let fromdate=21775;/*This is sas value for date 14AUG2019*/
%let xx = %eval(%sysfunc(&fromdate.)-1);
%let yy = %eval(%sysfunc(today())-1);
/
Like the error message tells you you're using %sysfunc() without using a function.
Code like below should do:
%let xx = %eval(&fromdate.-1);
Hi @Ronein
The %SYSFUNC() function enables to use SAS functions with macro variables.
In your example, the %SYSFUNC() function enables to use the TODAY() function. Look at the difference:
But in your example with xx, the %SYSFUNC() function is not associated with any SAS function. So that makes no sense.
The syntax should be just:
%let xx = %eval(&fromdate.-1);
Hope this help.
Maxim 1: Read the Documentation.
In this case, of the %SYSFUNC macro function. You will see that the first argument to %sysfunc has to be a function. Since &fromdate resolves to a literal and not a function name, your %sysfunc call fails.
