Hi folks - it could seems a silly question.
I have a varlist as a result of macroA.
%macroA;
...
%put &varlist;
%mend;
I need to use the created varlist in macroA in macroB as input.
but SAS errors me that &varlist is not recognised.
please help me in this regard....
The issue is variable scope.
A macro variable created within a macro, is local, it only exists within the macro. To use the macro variable outside of the macro you need to change the scope to global, as someone has already indicated.
%global varlist;
If you're creating a macro variable using call symput, change to call symputx and use the -g option.
Within %macroA, add this statement early:
%global varlist;
That will keep it around after %macroA ends.

Apart from using globals, you can make each call of the macro to be substituted
by the variables list as follows :
%macro macroA;
/* Code to generate the list */
[...]
&varlist
%mend macroA;
%macro macroB;
%let variables=%macroA;
[...]
%mend macroB;
thanks...
