Loading FLPA and MLPA

FLPA and MLPA are both loaded at IPL, and unlike PLPA, must be reloaded at each IPL. The systems programmer can control the contents of FLPA through the IEAFIXxx member in the logical Parmlib. MLPA is controlled through the IEALPAxx member, where xx is a two‑character parmlib member name suffix. Both of these members work in the same manner. A list of modules is specified along with the name of the library that each module is to be loaded from. There can be multiple LPA libraries. The entire concatenation is referred to in IEALPAxx or IEAFIXxx as SYS1.LPALIB. There can also be multiple LNKLST libraries that are similarly referred to collectively as SYS1.LINKLIB when specified in IEALPAxx or IEAFIXxx. The LNKLST concatenation can contain libraries that are not APF‑authorized. These libraries cannot load MLPA or FLPA. FLPA and MLPA can be loaded from any APF‑authorized library, and the real data set name should be specified.
