[I6] Adding grammar rules

On to my next newbie problem. The input to parse is “push paper under door”. Paper and door are existing objects. Standard output is “You can’t see any such thing.” because (I assume) “under” is not recognized as an object. I tried to hold off the parser with Extend 'push' first * 'under' -> MyPush; , but nothing changed. How can I insert my own additions, but let the Push command work normal for any situation I don’t care about?

You need to specify where the nouns go every time you define a grammar line.

Please try

Extend 'push' first * noun 'under' noun -> MyPush;

Works! Thanks!!
