#SETUP

The #SETUP macro is used to initialize the exit environment. Three parameters can be coded on the macro: BASE , AMODE , and RMODE .

BASE is used to indicate the base register for the exit driver module. The default is BASE=R12. Although no validation checks are made in the #SETUP macro, the value for BASE should be restricted to R2 – R12, inclusive.

AMODE is used to indicate the addressing mode of the exit driver module. The default is AMODE=31 . Valid values are AMODE=24 and AMODE=31 .

RMODE is used to indicate the residency mode of the exit driver module. The default is RMODE=ANY . Valid values are RMODE=24 and RMODE=ANY .

#SETUP macro usage examples might look like the following:

ICHPWX01 #SETUP BASE=R10,AMODE=31,RMODE=24
ICHPWX01 #SETUP

The label is required for the #SETUP macro.
