IBM SC34-6814-04 DFHTEPM TYPE=ENTRY and EXITfor user entry and exit routines, DFHTEPM TYPE=ERRPROCreplacing error processors

TACLE|NOTACLE
specifies whether the TACLEprefix is to be recorded on the transient data
destination.
TACLE
The 16-byte TACLEprefix as received from DFHTACP is logged.
NOTACLE
No TACLEprefix logging occurs.
ESE|NOESE
specifies whether the ESE associated with the error is to be recorded on
the transient data destination.
ESE
The ESE, after being updated, and before being deleted (if the action
puts the terminal out of service) is logged.
NOESE
No ESE logging occurs.
DFHTEPM TYPE=ENTRY and EXIT–for user entry and exit
routines
The sample DFHTEP provides guidance about how to prepare error processor
routines, particularly with regard to register and subroutine linkage conventions. The
routines must also observe the following restrictions:
vThe error processor must be coded in assembler language.
vThe first executable statement in the routine must be labeled TEPCDxx, where
“xx” is the error code specified in the DFHTEPM
TYPE=ERRPROC,CODE=errcode macro.
vRegister usage conventions and restrictions are stated in the sample DFHTEP
source.
vThe error processor must exit to the sample DFHTEP symbolic label TEPRET.
The macro required for a user “ENTRY” routine is:
This macro must be immediately followed by user “ENTRY” routine code, starting
with the label “TEPENTRY” and ending with a BR 14 instruction.
The macro required for a user “EXIT” routine is:
This macro must be immediately followed by user “EXIT” routine code, starting with
the label “TEPEXIT” and ending with a BR 14 instruction.
DFHTEPM TYPE=ERRPROC–replacing error processors
The macro necessary to replace error processors supplied with the sample
DFHTEP with user-written error processors is:
DFHTEPM TYPE=ENTRY
DFHTEPM TYPE=EXIT
DFHTEPM TYPE=ERRPROC
,CODE=errcode
(followed by the appropriate error
processor source statements)
