IMPLMAC | NOIMPLMAC

Syntax Description

IMPLMAC: causes the macro processor to examine the first word of every statement to see if that word is a statement-style macro call.
NOIMPLMAC: causes statement-style macro calls to be ignored. If the macro processor encounters a statement-style macro call when NOIMPLMAC is in effect, it treats the call as a SAS statement. The SAS compiler produces an error message if the statement is not valid or is not used correctly.

Details

The IMPLMAC system option controls whether macros that are defined as statement-style macros can be invoked with statement-style macro calls, or if the call must be a name-style macro call. These two statements illustrate statement-style and name-style macro calls, respectively:

name parameter-value-1 parameter-value-2;
%name(parameter-value-1, parameter-value-2)

Regardless of the setting of IMPLMAC, if the MACRO system option is in effect, you can call any macro with a name-style invocation, including those defined as statement-style macros.

PERFORMANCE NOTE: When you use IMPLMAC, processing time is increased because SAS checks every SAS statement to determine whether the first word is a macro call. When you use IMPLMAC with the MAUTOSOURCE system option, processing time increases because SAS also checks for a macro by that name in all macro autocall libraries that are defined in the SASAUTOS= option. When you use IMPLMAC and the MAUTOSOURCE system option with the MRECALL system option, processing time increases even further.
