How to use a created &varlist in %macroA in %macroB

[Moh]

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

[Astounding]

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;
