Dynamically binding or link-editing user exit routines z/OS DFSORT Application Programming Guide SC23-6878-00 |
|
You can dynamically bind or link-edit any user exit routine written in any language that has the ability to pass the location or address of a record or parameter in general register 1 and a return code in register 15 (see MODS statement). This does not include E15 and E35 user exits written in COBOL. Dynamic binding or link-editing does not
support AMODE 31 or RMODE 31 for the option T. The user exits that
are bound or link-edited together by
DFSORT are not loaded above 16MB virtual and cannot be entered in
31-bit addressing mode. User exits bound or link-edited
with the S option retain the AMODE and RMODE attributes of the object
modules and are loaded above or below 16MB virtual depending upon
the load module's RMODE; they are entered in the addressing mode of
the user exit.
Note:
When the option T is specified for a user
exit routine, that routine must contain an
entry point whose name is that of the associated program user exit.
This is to accommodate special DFSORT dynamic binder
or link-edit requirements. For example, when the option
T is specified on the MODS statement for E35, the following assembler
instructions must be included in the user exit routine associated
with the E35 user exit:
or
In all other circumstances, the user exit is not required to have an entry point that has the same name as that of the associated program user exit. |
