TOKDF DSECT
Cross Reference (Contains links to field and bit definitions)
TOKDF Prolog
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.
