Notes:
1. These parameters can be listed at IPL: APF, DUMP, FIX, ICS, MLPA, SYSP, and OPT.
2. The only mandatory parameter is PAGE. Other parameters have coded defaults.
3. Performance-oriented parameters in IEASYSxx: APG, CMD, FIX, IPS, MLPA, OPT, REAL, RSU,
WTOBFRS, WTORPLY.
4. System symbols in COMMNDxx and MSTJCLxx are processed differently than system symbols in
other parmlib members. See the descriptions of COMMNDxx and MSTJCLxx in this book for
details.
