How to conditionally %include a *.sas file that defines a macro? - sas

Question

I use a macro in several SAS programs, so I defined it in a separate file /myFolder/myMacro.sas.
When running in batch, I want to use it this way: %include '/myFolder/myMacro.sas;'
When testing changes to the code in Enterprise Guide, I wan to edit and run /myFolder/myMacro.sas, then edit and run the programs that use it. How do I conditionally include the macro definitions?
%if &server = BATCH_SERVER %then %include '/myFolder/myMacro.sas;' does not work: The file is included anyway and the %if statement is applied to the comment on top of the file and results in
ERROR: Expected %DO not found.
ERROR: Skipping to next %END statement.

Answer 1

Just use a %then %do
%let mode=BATCH;
filename mac1 temp;
filename mac2 temp;
data _null_;
file mac1;
put '%macro mac1;%put mac1;%mend;%mac1;';
data _null_;
file mac2;
put '%macro mac2;%put mac2;%mend;%mac2';
run;
%if &mode=BATCH %then %do;
%inc mac2;
%end;
%else %do;
%inc mac1;
%end;

Answer 2

As I suspected, the error occurs because the include file starts with comments, somthing like:
* MyMacro is written to do this and that *;
* ************************************** *;
%macro MyMacro;
proc this;
proc that;
run;
%mend;
So after including the file, this becomes
%if &server = BATCH_SERVER %then * MyMacro is written to do this and that *;
* ************************************** *;
%macro MyMacro;
proc this;
proc that;
run;
%mend;
which is invalid.
When working inside a macro: add %do; and %end;
As Allan suggested, it is sufficient to put the %inlcude between %do; and %end;
%if &server = BATCH_SERVER %then %do;
%include '/myFolder/myMacro.sas;'
%end;
So after including the file, this becomes
%if &server = BATCH_SERVER %then %do;
* MyMacro is written to do this and that *;
* ************************************** *;
%macro MyMacro;
proc this;
proc that;
run;
%mend;
%end;
which works.
When working in open code: use call execute
data _null_;
if "&mode"="BATCH" then call execute ("%include /myFolder/myMacro.sas;");
run;
%DoIt;
