     Name       : HCPTOKDF
     Description: Syntax token definition area
     DSECT      : TOKDF
     Function   : The TOKDF contains information that
                  describes what token is expected in a
                  syntax definition structure.  TOKDF is
                  used in conjunction with CONDF and STADF
                  to define a syntax tree.
     Created by : invocation of the DOSYN macro.
     References : HCPCLASS - User Class Categories
     Comments   : Note that TOKDF 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.
