     NAME       : HCPZLEBK
     DESCRIPTION: LOGO FILE LIST ENTRY BLOCK
     DSECT      : ZLEBK
     FUNCTION   : This is a DSECT of file information used by HCPBLO to
                  determine the appropriate logo for a specific device.
     LOCATED BY : HCPBOZ, HCPBLO .
     CREATED BY : N/A -- used to overlay ZLXVARS portion of a ZLXBK
                  block.
     DELETED BY : N/A
     NOTES      : The ZLEBK represents a fixed length block that is
                  imbedded in the ZLXBK ZLXVARS field.  No attempt
                  should be made to make this a variable length block.
