Operation
THIS MODULE WILL SET STORAGE PROTECT KEYS FOR A
BLOCK OF STORAGE OCCUPIED BY A SAVED SYSTEM. THE
STARTING ADDRESS MAY BE SPECIFIED BY THE CALLER AS
LONG AS IT FALLS WITHIN THE RANGE OF THE SYSTEM
LOAD EXTENTS.
DMSSSK VALIDATES THE KEY ENTRY IN THE PARAMETER LIST
BY ENSURING THAT IT IS A ONE OR TWO DIGIT NUMBER
BETWEEN 0 AND 15.
A FINDSYS IS THEN DONE FOR THE NAME PROVIDED WHICH
PROVIDES THE LOAD RANGE OF THE SAVED SYSTEM.
IF AN ADDRESS HAS BEEN INCLUDED IN THE PARAMETER
LIST, IT IS CHECKED TO ENSURE THAT IT FALLS WITHIN
THE LOAD RANGE OF THE SAVED SYSTEM.
THE COMPLETE RANGE OF THE SAVED SYSTEM MUST ALSO
FALL WITHIN THE V.M. STORAGE SIZE.
AN SSK INSTRUCTION IS THEN DONE FOR EACH 2048 BYTE
BLOCK IN THE RANGE SPECIFIED.
