Link-editing a C exit

Figure 74 shows sample JCL statements that can be used as a guideline for link-editing a C exit on z/OS®.

Notes:

PSFMVS.EXIT.PRELINK is the data set that contains the C exit code to be linked. The code is placed in this data set by the prelink JCL (see Figure 73).
C exit APSUC01 is link-edited into data set SYS1.PSF.EXITLIB.
