Hi,

My_SAS since the comparison is onmacro variable the condition should be macr condition and would involve macr if condition:-

data _null_;

%if &day=6;
%then %do;
x 'new.sh';
x 'old.sh';
%end;
run;

try this..

I have not tested this, but just looking at your code, it appears you have an extra semicolon. Try it without the semicolon after the "6". In other words:

if &day = 6 then do;

X statment cannot be executed from in a datastep. It can be executed conditionally through a macro as shown above.

In a datastep, use call system, or call execute with the x command inside.

data _null_;

if &day=6 then do;

call system('/path/to/new.sh');

call execute('x /path/to/old.sh');

end;

run;
