Note that these parameters are similar to those passed when DFHCSDUP
is invoked as a batch program. (See “Parameters passed from DFHCSDUP
to the user program” on page 815.) However, when DFHCSDUP is invoked
from a user program, the parameter list also includes the standard
parameters mentioned under “Parameters passed to the user exit routines”
on page 824.
Return codes
UERCNORM (X'00')
Continue processing.
UERCERR
Irrecoverable error. This causes DFHCSDUP to terminate with a
return code of ‘8’.
XPI calls
Must not be used.
The put-message exit
The put-message exit is invoked whenever a message is to be issued. If you are
running under TSO, you could use this exit to terminate DFHCSDUP after the
operator inputs an ATTENTION interrupt. (See “Invoking DFHCSDUP from a user
program” on page 821.) Or you could use it to provide messages in the operator’s
national language.
Even if this exit is supplied, messages are always additionally written to the default
output file (that is, to SYSPRINT, or to the replacement ddname specified on the
entry linkage to DFHCSDUP).
When invoked
Invoked when a message is to be issued.
Exit-specific parameters
UEPMNUM
Address of a 4-character field containing the message number
