 NAME       : HCPSYNDF
 DESCRIPTION: Syntax definition description area
 DSECT      : SYNDF
 FUNCTION   : The SYNDF acts as a root of the syntax tree
              defined by the invocation of the HCPDOSYN
              macro.  The HCPDOSYN macro, in turn, creates
              the syntax tree based on invocations of
              HCPCFDEF, HCPSTDEF and HCPTKDEF macros.
 CREATED BY : invocation of the HCPDOSYN macro.
 RELOCATION CONSIDERATIONS : None
