[developers] Question on using PET/ACE for parsing

Hi Prof. Oepen,
I have tried using the command such as 'echo 'this is a _generic_vbd_ .' |
./bin/cheap -default-les=all -cm lingo/erg/english.grm' on the top level of
logon, but have had no luck. Cheap outputs that it did not find any lexicon
entries for '_generic_vbd_'.
One thing that I am noticing is that if I look in the _generic_vbd_ entry
in the linguistic type database (link
and choose any surface form listed to replace the word in the sentence, it
will activate the generic_vbd rule, and not any other rule. Could there be
any potential downsides to using this method?
Again, I really appreciate your time! Thanks!
