IF and ENDIF Directives
IF and ENDIF Directives
IF and IFNOT control conditional compilation based on a condition. The ENDIF 
directive terminates the range of the matching IF or IFNOT directive. The D20 or later 
RVU supports named toggles and target-system toggles as well as numeric toggles.
INHIBITXX Directive
INHIBITXX generates inefficient but correct code for extended global declarations in 
relocatable blocks that Binder might locate after the first 64 words of the primary global 
area of the user data segment. The default is NOINHIBITXX.
INNERLIST Directive
INNERLIST lists the instruction code mnemonics (and the compiler’s RP setting) for 
each statement. The default is NOINNERLIST.
