This parameter asks that the system warn when finding an undefined
system parameter rather than prompt for new system parameters. When
the WARNUND parameter is found, it applies to all subsequent system
parameter processing. If you want WARNUND processing for all IEASYSxx
parmlib members, IBM® suggests
that you put WARNUND at the beginning of IEASYS00 so that it covers
all subsequent system parameters within IEASYS00 and any other IEASYSxx
members processed. If you only need WARNUND processing before a specific
parameter in an IEASYSxx member, you can place WARNUND just before
that parameter. If you want WARNUND processing for your reply to IEA101A
SPECIFY SYSTEM PARAMETERS, you must specify it within the reply text
(earlier within that reply than any unknown parameter). For example,
you might reply:
R 0,WARNUND,SYSP=01,NEWPARM=VALUE
Note: WARNUND only applies to primary system parameters that
are listed in IEASYSxx and not to their associated sub-parms.
IBM suggests that you avoid using
unknown parameters within this reply text that imply that you do not
need WARNUND within the reply text.
