This variable indicates whether or not leftover LUs
will be made available to tn3270 sessions which
do not request a specific LU or LU pool.
A 'leftover' LU is defined as one for which all of
the following conditions hold true:
.the SSCP did not send an ACTLU during PU startup; and
.the PU controlling the LU is capable of carrying PSID
vectors on NMVT messages (thus allowing DDDLU
operation for that LU).
inherit indicates that the value of tn3270sPuGenericPool is
to be the same as tn3270sGlobalGenericPool.
deny indicates that the leftover LUs should not be given
to a generic pool (ie, the PU is not automatically
fully populated with 255 LOCADDR definitions);
permit indicates leftover LUs should be made available to
tn3270 users wanting 'generic' sessions. All LUs in the
generic pool are (by definition) DDDLU capable.
