Rune,

I hope that this is a example.  Simply put you are doing three things wrong.
  First you are %including the SAS code which seems silly to me, it would
make more sense to just compile and store the thing that way.  Secondly, You
havent invoked the macro yet but you are trying to use the macro variable
that whould be produced by your macro.  Thirdly, this macro var created by
your macro if you invoke it will local unless you have already defined the
macro as global before you invoke this macro.

And no you dont have to make the dang macro var global at all.  That is just
a poor understanding of macro language and usage.  In your case all you need
to do is one rewrite your macro definition to :

%macro create_macro_variables ;
%local myname ;

      %let myname = Rune ;

      &myname
%mend ;



And in your program if yo insist on %including the code:


%include "D:\SAS_KODE\utvikling\create_macro_variables.sas" ;


%put The macro variable 'myname' resolves to : %create_macro_variables ;

Hi,
This is how the file CREATE_MACRO_VARIABLES.sas looks like:

%macro create_macro_variables;
      %let myname = Rune;
%mend;

And this is how the file MAIN.sas looks like:

%include "D:\SAS_KODE\utvikling\create_macro_variables.sas";

%put The macro variable 'myname' resolves to : &myname;


This is what the log tells me:
%put The macro variable 'myname' resolves to: &myname;
WARNING: Apparent symbolic reference MYNAME not resolved.
The macro variable 'myname' resolves to: &myname

I have also tried to write %global myname; outside the macro in the the
file CREATE_MACRO_VARIABLES.sas, but it doesn't help. Writing %global
myname inside the macro didn't help either.

Does this problem have another solution than just omitting to give
macro variables values within a macro ?

Regards, Rune
