Problem with macro reference

[_AW_]

Hello. I'm running into a problem where the first time I submit the following code, the macro MAIN is not being executed (the log is also here). However when I submit the second time it calls MAIN without a problem.

I've read things about the step boundary, but I'm curious why this does not execute the first time, but does the second. If I exit SAS and re-open again, the first time I execute the program I get the same problem again. It's only on the second and any subsequent executions that MAIN executes.

I also run into the same problem with the second set of macros being called (found in MAIN). But that takes until my third run before they execute without error.

I'm SAS 8E, if that makes a difference.

Thanks. AW

CODE:

%let path = N:\PUBLIC\PN_PA\Andy\Per Diem\SAS programs\Macro;

/*options symbolgen mlogic;*/

data _null_;
do curyear = (input(substr(put(today(), mmddyy10.),7),4.)-1) to 2005 by -1;
call symput('curyear', curyear);
call execute('%main(year=&curyear)');
end;
run;


%macro main(year=);
%do i = 2 %to 6 %by 1;
%if &i eq 1 %then %let type = driver;
%else %if &i eq 2 %then %let type = senior;
%else %if &i eq 3 %then %let type = rehab;
%else %if &i eq 4 %then %let type = ltac;
%else %if &i eq 5 %then %let type = snf;
%else %if &i eq 6 %then %let type = acute;
%else %put 'Error in Main Macro process - variable TYPE did not resolve';
%&type(year=&year,type=&type);
%include "&path.\&type..sas";
%end;
%mend main;

It looks like I've found the answer to my problem. Since the macros were not in WORK.SASMACR they could not be found by the call intially. However the first time the program was run it created a compiled version in WORK.SASMACR.

I was able to get this to work by creating compiled versions of each of the macros in a directory that I specify and then use in OPTIONS MSTORE SASMSTORE =.

The given macro needs to be run once in order to be compiled. Once it is compiled SAS can find the macro that is being called.

If you want to use a macro without the extra step of a compiled library, just put the definition of the macro before it's first invocation.
