CP Loadlist Requirements
TheCP loadlist EXEC contains a list of CP modules used by the VMFLOAD procedures when punching the text decks that will make up the CP system.
All modules followingDMKCPE in the list are pageable CP modules. Each
4K page in this area may contain one or more modules. The module
grouping is governed by the order in which they appear in the loadlist.
AnSPBt (Set Page Boundary) card, a loader control card placed in the
text file, forces the loader to start this module at the next higher 4K
boundary. The loader automatically moves a module to the next higher 4K
boundary if it cannot fit in with its predecessors on the load list. In
this case a message is placed on the load map:"SPB INSERTED" as part of the line "**EXTERNAL SYMBOL DICTIONARY FOR DMKXXX" An SPB card is required only for the first module following DftKCPE. If
more than one module is to be contained in a 4K page, only the first canbe assembled with an SPB card. The second and subsequent modules for a
multiple module 4K page must not containSPB cards.
The position of two modules in the loadlist is critical. All modules
followingDMKCPE must be reenterable and must not contain any address
constants referring to anything in the pageableCP area. DftKCKP must be
the last module in the loadlist.
The following modules are distributed withSPE cards: DMKCDB DMKCKP DMKCPI DMKCPS DMKCPV DMKPGS DMKSAV DMKSEV DMKSYM DMKTAP DMKVSI lA 12-2-9 multipunch must be in column 1 of an SPB card and the
charactersSPB in columns 2, 3, and 4 respectively.
