Hello everyone,
I want to use an alternative method to simplify "%if (&a=1 or &a=2 or &a=3)" in macro %test in the SAS code below
The %test macro works but the %test2 will cause error, the error parts caused by "%if &a in (1,2,3) %then....."
Please advise.
Thanks!
Mike
%macro test(a);
%if (&a=1 or &a=2 or &a=3) %then %do;%put a=1/2/3;%end;
%else %do;%put a=other;%end;
%mend test;
%test(a=2);
%test(a=5);
%macro test2(a);
%if &a in (1,2,3) %then %do;%put a=1/2/3;%end;
%else %do;%put a=other;%end;
%mend test2;
%test2(a=2);
%test2(a=5);
you need to turn in 'on' in SAS for macros:
options minoperator;
See this SAS Note:
Thank you Reeza,
very impressive solution (I will try it later,) but I use SAS9.1 which not support this nice option .
I find that using indexw is just as easy and compatible with older versions of SAS.
%if %sysfunc(indexw(1 2 3,&a)) %then %put a=1/2/3;
%else %put a=other;
Awesome!
thank you Tom,
