Other Host-Specific Aspects of the Macro Facility

Character Encoding for Evaluating Macro Characters

Under z/OS, the macro facility uses an EBCDIC character encoding for %EVAL and for the automatic evaluation of macro characters. For example, 
%EVAL(“A”)
evaluates to the integer 193 (hexadecimal C1) because this value is the code point for the character A in the EBCDIC character set.

SAS System Options Used by the Macro Facility

The following table lists the SAS options that are used by the macro facility and that have host-specific characteristics. It also tells you where to look for more information about these system options.
