Hello Hans
Thanks for the reply.
So you need to assign config_spec a valid value somewhere, or write a
rule that initializes $$ instead of the default rule.
Does that mean it is possible to redefine the default rule from
"$$ = $1;" to e.g. "$$=NULL;" ?
Can you tell me how ? I did not find anything like that in the
documentation.
Thanks für your help.
Best regards,
Michael
