 NAME       : HCPVFPBK
 DESCRIPTION: Vector Facility Paramaters Control Block
 DSECT      : VFPBK
 FUNCTION   : The Vector Facility Parameters control block
              (VFPBK) contains information supplied by the user via
              the DISPLAY/DUMP/STORE Vector commands. The parameters
              are set in HCPCDFCP and are used in HCPVFSTO and
              HCPVFDDC. The VFPBK is also used to include vector
              information in guest storage dumps. In this case the
              parameters are set in HCPCDPDM and used in HCPVFDDC.
 LOCATED BY : N/A
 CREATED BY : N/A
 DELETED BY : N/A
 SERIALIZED : N/A
 Notes      : When used for vector commands, this control block
              overlays a buffer in HCPCDFCP. When used with guest
              storage, this control block overlays a buffer in
              HCPCDPDM.
