NAME : DMSCDEV
DESCRIPTION: CONSOLE DEVICE TABLE MAPPING
DSECT : CDEV
FUNCTION : THE CONSOLE DEVICE TABLE IS A LINKED
LIST OF DEVICE ENTRIES CONTAINING INFORMATION
ABOUT DEVICES OPENED TO A PATH BY THE CONSOLE
FACILITY. A DEVICE ENTRY IS DELETED WHEN AN
APPLICATION ISSUES A CONSOLE CLOSE AND NO OTHER
PATHS ARE OPENED TO THAT DEVICE.
DEPENDENCIES - FIELDS CONTAINED WITHIN THE CDEVCQY STRUCTURE
MUST MAP 1 FOR 1 WITH THE FIELDS IN THE DEVICE
SECTION OF THE CQYSECT MA PPING MACRO. ANY
CHANGES MUST BE CHECKED AGAINST CQYSECT.
