     Name       : HCPZSBBK
     Description: Storage mapping for the results of
                  parsing a TYPE=STORANGE token
     DSECT      : ZSBBK
     Function   : Mapping for output from parsing a TYPE=STORANGE
                  token.
     Located by : Registers in CP Parser code and post-processors
     Created by : None
     Deleted by : None
     Serialized : None, this is simply a mapping
     Notes      :
                  This mapping is for use by both CP and CP Exits.
                  (*) IBM reserves the right to increase the number
                  of characters supported (currently 15 characters
                  are supported of which 14 of these are numeric and
                  the 15th is the scaling character) for each
                  subtoken of a storage range specification.
     Format of a  oken of TYPE=STORANGE (one token, no blanks):
     ssssU-ddddV. lllW
     where: ssssU is converted from a scaled decimal value and
                  placed in the 'start' portion of the mapping.
                  An example is included in the mapping as a
                  guide to how this is done.
                  ddddV is converted from a scaled decimal value and
                  placed in the 'decrement' portion of mapping.
                  llllW is converted from a scaled decimal value and
                  placed in the 'size' portion of the mapping.
                  'U', 'V', and 'W' are scaling characters:
                  'K' means Kilobytes
                  'M' means Megabytes
                  'G' means Gigabytes
                  'T' means Terabytes
                  'P' means Petabytes
                  'E' means Exabytes
     The number o digits in "s", "d", and "l" must be <= 14 (*)
     and the valu must successfully convert to a doubleword
     hex value af er scaling.
     Note that "0 can mean absolute 0 or 16E.  Applications
     must be able to distinguish between these values using the
     semantics of the command or statement being parsed.
     There is no  arser significance to 'start', 'decrement',
     and 'size'.  However these are the uses of these subtokens
     by the CP DE INE STORAGE CONFIG command.  See that command's
     syntax and s mantics for additional information.
