Subject:      Macro LET statement equivalent of Call Symput;
Comments: To: sas-l@uga.edu

Hi ,

I have a problem in the following code. I need to create dynamic
libname statements like the following:

libname admin200201 'd:\vfs\store\200201'; /* These are existing
folders */
libname admin200202 'd:\vfs\store\200202';
libname admin200203 'd:\vfs\store\200203';
....
...
..
libname admin200201 'd:\vfs\store\200312';

When I execute the code, the macro variable YM , is not resolved in the
first run, as I've used call symput, which effectively creates the YM
variable after the datastep execution. How do I convert the CALL SYMPUT
STEP into a legal %let statement , so that I create the variable before
I create my Libname statment. Am I right in finding this issue or is
there any other error in the macro logic? :(

Thanks
Moorthy

%do j=&sm %to &em;

symput('ym',substr(put(intnx('year','01jan01'd,&i),ddmmyy10.),7,4)!!
           trim(left(trim("0")||left(trim(&j)))));
%let lib=libname admin&ym "d:\vfs\store\&ym";
%put &lib;
%end;
%end;
run;

%mend t;

%t(sy=1,ey=2, sm=1, em=12);
