BDI System Generation Parameters
D.2. BDI System Generation Parameters
There are two system generation parameters that indicate the number of fixed or
dynamic BDIs allowed. They are MAXBDI and APLDYNBDS, respectively. This
subsection also identifies the highest-numbered BDI that might be referenced by basic
mode programs.
D.2.1. MAXBDI
MAXBDI is an Exec system generation parameter that indicates the maximum number
of fixed BDIs permitted. Its default, and recommended value, is 3121 (06061). If a value
other than the default is selected, the allocation of BDIs (as described in this appendix)
must be adjusted accordingly. In addition, application level products which have been
given a fixed BDI greater than the selected MAXBDI will not function properly on the
system.
D.2.2. Basic Mode BDIs
BDI number 4095 (07777) has special significance. This is the highest-numbered BDI
that might be referenced by basic mode programs. Thus, 4095 becomes a line of
demarcation separating basic mode banks, as well as those extended mode banks which
must be accessed by basic mode programs, from banks which are exclusively extended
mode.
