This parameter specifies the EXITxx members of parmlib that contains
the entry points and names of allocation installation exits. The two
alphanumeric characters, represented by aa, are appended to EXIT to
form the name of the EXITxx members.
Note: IBM® provides the PROGxx member as an alternative
to EXITxx. IBM suggests that
you convert the format of EXITxx to PROGxx and provides the IEFEXPR
REXX exec to do this. You should also add the PROG=xx system parameter
to IEASYSxx (see PROGxx (authorized program list, exits, LNKLST sets and LPA)), remove the
EXIT=xx system parameter from IEASYSxx, and remove EXIT=xx from IEASYS00.
For information about how to begin using PROGxx, see PROGxx (authorized program list, exits, LNKLST sets and LPA).
