NAME       : HCPSTADF
 DESCRIPTION: Syntax state definition area
 DSECT      : STADF
 FUNCTION   : The STADF contains information that describes a state
              that the syntax checking is in.  It indicates whether
              a token match is optional or not.  STADF is used in
              conjunction with CONDF and TOKDF to define a syntax
              tree.
 CREATED BY : invocation of the HCPDOSYN macro.
 REFERENCES : None
 RELOCATION CONSIDERATIONS : None
 COMMENTS   : Note that STADF entries are unaligned.
              This requires that all of the DSs that would normally
              enforce alignment (like A and F) must specify an
              explicit length attribute in order to skip alignment.
