 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.
