CONDF Prolog

 Name       : HCPCONDF
 Description: Syntax statement definition area
 DSECT      : CONDF
 DSECT      : CONDF
 Function   : The CONDF contains information that describes a
              statement verb, its minimum abbreviation and the name
              of its post-processor address.  CONDF is used in
              conjunction with STADF and TOKDF to define a syntax
              tree.
 Created by : invocation of the HCPDOSYN macro.

 References : HCPICRBK - Indirect Call Request Block
              The CONDF contains storage that is mapped by the
              ICRBK DSECT.  This storage is to enable indirect calls
              typically only used if EXTERNAL_SYNTAX statements are
              used.
 Comments   : Note that CONDF entries are unaligned.
              This requires that all of the DCs that would normally
              enforce alignment (like A and F) must specify an
              explicit length attribute in order to skip alignment.
