Exit-specific parameters
UEPARG
Address of the EXEC command parameter list.
UEPEXECB
Address of the system EIB.
UEPUSID
Address of the 8-character userid.
UEPPGM
Address of the 8-character application program name.
UEPLOAD
Address of the application program's load-point.
UEPRSA
Address of the application's register save area. This contains the
contents of the registers at the point when the program issued the
EXEC CICS command.
UEP_EI_PBTOK
Address of a 4-byte field containing the z/OS Workload Manager
(WLM) Performance Block Token. An exit program can use this
token to access information (such as the service class token,
SERVCLS) in the WLM Performance Block. To do so, it must use
the WLM EXTRACT macro, IWMMEXTR, passing the Performance
Block Token as the MONTKN input parameter. For more information
about the IWMMEXTR macro, see z/OS MVS Programming:
Workload Management Services.
An exit program must not attempt to modify the Performance Block:
if it does so, the results are unpredictable.
Return codes
UERCNORM

UERCBYP
