macro variables and proc inside module definition

deleted_user — Tue, 22 Dec 2009 16:53:57 GMT

I have two questions:
1. How is it possible to define macro variables inside implus language? Why &macro_var_name is not referenced in implus language if %let is put inside submit/endsubmit statements?

submit;
%let pippo={1 2, 3 4};
endsubmit;
x=&pippo; <--error

2. Is it possible to include a proc of SAS STAT inside a module?For example I need to insert proc corr inside a module for defining objective function of a genetic algorithm.

Thanks in advance,
Angela

In answer to your questions:

(1) IMLPlus does not support SAS macro variables except inside submit blocks. However, you can use the Base SAS functions symgetn and symgetc. For example:

submit;
%let xyz = 123;
endsubmit;

x = symgetn( "xyz" );
print x;

(2) Yes, you can call any SAS procedure (except PROC IML) from inside a submit block that is itself inside an IML module.
