Prerequisite APARs or PTFs need to be applied to your system before
you can apply the current maintenance. These APARs or PTFs might apply
to High Level Assembler or any licensed program you have installed
at your site.
Your IBM® Support Center has
given you a list of any relevant prerequisite APARs or PTFs. Probably
most have been applied to your system. You can verify this by retracing
the APARs and PTFs in your system history file. The job shown in Figure 1 shows how to retrace APARs and PTFs
in the system history file. This job is supplied as ASMARETR.Z
Use this listing to check that you have already applied any pre-requisite
APARs or PTFs. If you have not, arrange for your IBM Support Center to send them to you and apply
them before applying other service. Figure 1. Job to retrace APARs and PTFs
