Operation
TYPE 1 - LOCATE A MODULE
DUMPSCAN PASSES 'MOD' THE ADDRESS OF THE PLIST
THIS POINTS TO A MODULE NAME. MOD READS IN A SHORT
FORM OF THE LOAD MAP FROM THE END OF THE DUMP,
SCANS FOR THE NAME, GETS THE ADDRESS OF THE MODULE AT
IPL TIME, CHECKS THROUGH THE SEGMENT AND PAGE TABLES
TO FIND WHERE IT WAS LOADED AT DUMP TIME.
IT THEN CALLS GETREC TO FETCH THAT AREA INTO CORE,
AND CALLS DIR TO DISPLAY IT.
TYPE 2 - FIX AN ADDRESS
DUMPSCAN PASSES MOD AN ADDRESS. THIS IS VALIDITY
CHECKED THEN A SEARCH IS MADE TO FIND THE CODE WHICH
CONTAINS THE ADDRESS. FIRST THE ADDRESS IS CHECKED
TO SEE IF IT IS ABOVE DMKCPEND. IF NOT, THE NAME IS
EXTRACTED FROM THE LOAD MAP. IF IT IS, THEN THE PAGE
CONTAINING THE ADDRESS IS BROUGHT INTO CORE. THE PAGE
IS SCANNED FROM THE ADDRESS BACK, UNTIL A MODULE NAME
IS FOUND. THE MESSAGE IS CONSTRUCTED TO GIVE THE
MODULE NAME AND DISPLACEMENT.
