Hello Terence,

thanks for your answer!
I know, I know your students and the end of the year....

Attached you will find a pdf-file which explains my problem -
state-of-the-art highlighted in colour!
And then there is still the question:
   <ruleDescriptor.name> and <ruleName> what is the difference?

I asked Jim already - I just copied his template-dir, renamed the
file C.stg to CRtMod1a.stg and added my "pathfinder"-comments
beginning with //! , followed by tg__ (test grammar) or tt__
(test template). Only the *.c-file is generated, the *.h-file
is missing. Why?


Again many thanks and greetings
Udo
