Array with &

GN0001 — Wed, 11 May 2022 21:08:49 GMT

Hello team,
I have an array with this structure:
array mbrreq {*} &mbr. ;
What is &mbr.?
Is it a macro call? Or a macro variable which takes in the elements of this array?
Regards,
Blue&Blue

Perhaps a macro variable with multiple variables as strings.

For example, I think it is below.

%let mbr=mbr1 mbr2 mbr3;
%let mbr=mbr:;

The macro variable (it's not a macro call, because those start with a percent sign) can contain anything that is valid code at this place. It must contain a list of variable names (because of the asterisk), but it could also contain a $ sign (or VARCHAR) to specify a character array, and it could also contain a list of initial values.

If you want to know what is actually used, add a

%put &mbr.;

statement right before the ARRAY statement.

To see what may appear in the macro variable, study the documentation of the ARRAY Statement.
