Abstract: zSoftCap is a PC-based productivity tool designed to assess the effect on capacity for IBM System z processors, when migrating to more current releases of the operating system or major subsystems. zSoftCap assumes that hardware remains constant while software releases change.

Any version of zSoftCap prior to C4.5 MUST be uninstalled prior to installing zSoftCap version C4.5a.
This is necessary to facilitate conversion to the new Java V7 runtime environment.
