Detailed Description

Reports a failure in the log and returns 0. It never aborts: an mf_ macro returns a value, and ending the step here would leave the caller unable to see that value or to report the failure itself. Usage:

%let var1=x;
%let var2=y;
%put %mf_verifymacvars(var1 var2);

Returns:

1

Parameters

[in]	verifyvars	Space separated list of macro variable names
[in]	makeupcase=	(NO) Set to YES to convert all variable VALUES to uppercase.
[in]	mAbort=	(SOFT) Retained for backwards compatibility. The macro no longer aborts on any value - a failure is written to the log and 0 is returned, so the caller decides what to do with it.

Note

will not be able to verify the following variables due to naming clash!

• verifyVars
• verifyVar
• verifyIterator
• makeUpcase
