Irrecoverable error. This causes DFHCSDUP to terminate with a
return code of ‘8’.

The sample program, DFH$CUS1
The CICS-supplied sample program, DFH$CUS1, illustrates how DFHCSDUP can
be invoked from a user program. It is written as a command processor (CP) for
execution under the TSO/E operating system.
Note that DFH$CUS1 uses different DCB and ACB names from those normally
used by DFHCSDUP. Ensure that these are allocated before running the program
under TSO/E.
Although DFH$CUS1 is intended to be run from TSO, you can also run it from, for
example, a REXX EXEC. Before doing so, ensure that the load library that contains
DFH$CUS1, DFHCSDUP, and DFHEITCU is in the user's search chain, LOGON
proc, or linklist. Figure 132 is an example REXX EXEC that invokes DFH$CUS1.
