 DESCRIPTION: Relocation mapping for HCPFINBK
 DSECT      : $FINBK
 FUNCTION   : LGRFINBK describes those fields of the FINBK that
              will be migrated to the destination system during
              guest relocation.
 LOCATED BY : This is a mapping of the RDODATA area within the
              RDOBK during guest relocation.
 RELOCATION CONSIDERATIONS : This control block is used during live guest
              relocation.  It is used to relocate a control block
              defined in a corresponding HCP COPY file.  Any
              fields or bits defined in HCPFINBK which are
              required on the destination system must be defined
              here, and code must be added to migrate the field
              or bit during a relocation.

These bits are defined sequentially, regardless of how they are defined in HCPFINBK. This yields a consistent mapping that ensures compatibility when a guest is relocated between systems at differing service levels. Names in the comments column indicate the control block byte which contains the flag. This name is subject to change if the flag definition changes. ====> NEVER change bits which already exist here. ====> NEVER change the order of bits in this section. ====> ALWAYS add new bits at the end of this section, together with new flag bytes as required. 0008 8 Signed 2 $FIN_BITS (0) Bit map area 0008 8 Bitstring 1 $FIN0 1... .... $FINFPIUC X'80' $FINFPIUC FINFIUCV .1.. .... $FINFPVMC X'40' $FINFPVMC FINFVMCF 00000001 $FIN_BLEN *-$FIN_BITS Length of bit map area Data: Contains all HCPFINBK data that is subject to relocation, except for flag bits, which are handled separately.
