PSZ allows for the easy creation/removal of COMMON partitions. It is especially useful on RSX11M systems used for program development; where testing different applications requires frequent shuffling of common partitions in and out of memory. PSZ will create a COMMON partition in the smallest memory hole in which the partition will fit; if there is no such hole, it will attempt to shrink GEN and put the common on top of GEN. When a partition is removed, PSZ makes GEN as large as it can. PSZ can also be used to change the size of existing partitions, in a variety of ways (see PSZ.HLP). PSZ has been tested extensively under versions 3.2 and 4.0 of RSX11M. This version of PSZ is presented by RGTI Systems Software 1 Penn Plaza, rm. 4310 NY, NY 10001 (attn: Ross Amann, 212-695-5001) This is a heavily modified version of the PSZ on the fall 81 RSX SIGtape under UIC [300,125] (by Rodger S.
