Superseded SYSMODs
When one SYSMOD is superseded by another, SMP/E makes a record
of this by adding the name of the superseding SYSMOD to the entry
for the superseded SYSMOD.
- When there is only one superseding SYSMOD, its name is saved in the LASTSUP subentry.
- When there are several superseding SYSMODs, the name of the last one is saved in the LASTSUP subentry, and a complete list is saved in the SUPBY subentry.
If the superseded SYSMOD has not been previously applied, its target
zone SYSMOD entry contains only the LASTSUP information. Such a SYSMOD
entry is called a dummy entry
. Because the superseded SYSMOD
had not been previously applied,
SMP/E does not know what
type of SYSMOD it was (function, PTF, APAR, or USERMOD).
