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....

Could you please let us know how you are using the &varlist in macro B. Is the macro variable &varlist resolving

Within %macroA, add this statement early:

%global varlist;

That will keep it around after %macroA ends.

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.

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;
