VFPBK Prolog
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.
