A PL/I version
The sample job in Figure 109 shows the link-edit statements you need for a PL/I
version of a DFHCSDUP user program.
Notes for the PL/I job:
1 Specify the entry name as DFHEXTRA, which is the entry name in the
CICS-supplied stub, DFHEXPI (see 3).
2 The CICS-supplied stub, DFHEXPI, is generated with a link to the user program
using a dummy CSECT name (EXITEP). Use the link-edit CHANGE statement to
change the CSECT name from EXITEP to the name specified on the PROC
statement in the PL/I user program. In the two CICS-supplied PL/I sample
programs, these names are:
CREFCSD
The PROC name in DFH$CRFP, the cross-reference listing user program.
FORMCSD
The PROC name in DFH$FORP, the DB2-formatting user program.
3 Include DFHEXPI in any PL/I language user program that you write for use with
the DFHCSDUP EXTRACT command. DFHEXPI is the interface stub between
DFHCULIS, a module in DFHCSDUP, and the PL/I user program.
4 Include the PL/I dummy program, DFH$PDUM, to establish the PL/I
environment, and enable the PL/I user program to run as a subroutine. Before you
can include DFH$PDUM, by specifying it on the INCLUDE statement as shown, you
must compile it using your PL/I compiler. The compiled version of the dummy
program must be included in one of the libraries available to the linkage editor (for
example, SYS1.PLI.PLIBASE).
5 obj-prog is the name of the object program.
6 progname is the name you want for the load module; this is the name that you
specify on the USERPROGRAM parameter of the EXTRACT command.
