IDMBK Prolog

 NAME       : HCPIDMBK
 DESCRIPTION: Spool Image Library Directory Member
              Entry Block
 DSECT      : IDMBK
 FUNCTION   : To map out the directory member information
              in a 3800 image library file.
 LOCATED BY : The directory members are located after
              the IDHBK on the first directory record in
              the file. The IDHNUMDE determines how many
              IDMBKs there are on the directory record(s).
 CREATED BY : IMAGELIB command (HCPNMTBL)
              IMAGEMOD command (DMSIMAGE)
 DELETED BY : All the contents of an IMG file, including
              the IDMBKs, are deleted by the "PURGE IMG"
              command processing (HCPCSUPU).
