Macro variable within a macro variable

Lupacante — Fri, 13 Jun 2014 12:51:56 GMT

Hi all,

I have the following macro variables:

day_1_start = 'something'

day_2_start = 'somethingelse'

I am now trying to call them in a loop, and so (within a macro loop) have

%do i = 1 %to 5;

var = var * &day_&i._start ;

%end;

but it's not working. The log says 'WARNING: Apparent symbolic reference DAY_ not resolved.'

Any advice?

Thanks,

Marco

Put an extra & in from of &day:

var = var * &&day_&i._start ;

That causes the first pass to resolve to &day_1_start, and the second pass resolves to something.
