You are making a mistake. Get yourself an accurate spool checker from the
VM-UTIL filelist or a workshop tape or whatever. The one used by LMON is
inaccurate, giving a gross overestimate of the amount of spool space in
use (it reads the counters maintained by CP, which are totally broken
under non-XA systems). Determining the exact spool utilization under SP
and HPO involves scanning control blocks whose format varies with the
release, flavour (SP vs HPO), type of disk (CKD vs FBA) and, sometimes,
service level. The program usually goes into a loop if the control blocks
are not the way it thinks they are, so I refused to use anything that
sophisticated in LMON. The result is that it can be off by 50% or more,
and complain that the spool is 95% full when you have just purged half of
the files. IBM fixed this problem in XA: I still read the CP counters
(using a different and incompatible method), but this time they are
accurate. By the way, SEARN runs VM/SP 5.
