I encountered a problem installing a previous*pacakge, where required PTF's, which supposedly
were shipped with the tape needed to be installed before the HIPER PTFs, but couldn't be because
they were not accessable.
I overcame this by using the IBM dialin line to downloaded some of the required PTFs. By performing
option 8 (Cumulative) from the menu and selecting *SERVICE as the origin, the downloaded PTFs
were installed or failed to install because of other missing PTF's.
This whole process was repeated about 4 times before all of the required PTFs were installed
on the system and the HIPERs could be installed, and then finally, all other PTFs. All up,
about 9 IPLs were performed.
