NAME : HCPIMHBK
DESCRIPTION: Spool Image Library Member Header Block
DSECT : IMHBK
FUNCTION : To map out the member header information
preceding each member in the 3800 image
library file.
LOCATED BY : The member header preceeds each image module
in the image library. It is pointed to by the
IDMDISP field in the IDMBK.
CREATED BY : IMAGELIB command (HCPNMTBL)
IMAGEMOD command (DMSIMAGE)
