Hi, I need to check if a variable (word) is assigned, how can I do?
Example: > a: 100 > assigned? a true > assigned? b false (obviously, "assigned" is a term I invented because I don't know how I can = do!) I partially solved the problem using try [] block (if a word does not exists, then an exception is thrown), but I don't like it. Can you help me?
