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).
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) Dynamic Definition of
Dependant (DDDLU) capable.
