[REBOL] Check if a path exists?

From: stefan:falk:slg:se at: 21-Mar-2001 11:59

Hi list, how can I check if a path has a value. I've decode some cgi into objects, something like this: data/name data/comment Now, if I want to check if there's actually something in data/comment (as it sometimes isn't), how should do? comment: data/comment if (length? comment) > 0 [ some code...] doesn't work... and if exists? data/comment doesn't work either.. Any tips? /Regards Stefan
