EXIT

EXIT=aa 
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).

Value Range: Any two alphanumeric characters.

Default Value: None

Associated Parmlib Member: EXITxx
