run same macro many time with different parameters

jojo — Mon, 10 Dec 2012 20:57:44 GMT

I need to run the same macro CT 50 times changing just one of the several parameters. A, B, C...... are 50 variables that need to be replaced in the call macro.

%CT(param1=data, param2=inv, param3=A);

%CT(param1=data, param2=inv, param3=B);

%CT(param1=data, param2=inv, param3=C);

.....

Copy and paste works well

or consider using a macro do / while loop

I like Barry's 1st answer and below is how you would do for his second suggestion.

get the list of variables that needs to be passed to the macro and send them all to a macro variable separating them by a special character, say LIST for example:

the macro variable LIST would be like this A*B*C*D*............*Z

now loop it through all the parameters

%do i=1 %to 50;

%let param=%scan(&list,&i,'*');

%CT(param1=data, param2=inv, param3=&param);

%end;

hope this helps.

You can have you parameters stored in a SAS table, and call the macro by using call execute instead.
