I did in BASIC with a particular bug in TRANSFORM though, and it was so bad I couldn't even bring it back with INIT:3.

There's always one in every crowd, and in this case a very lucky one! I suspect you may have experienced this in the beginning, but it's been so long it feels like it didn't happen.

The important thing is you kept going and before too long you were replacing many of the ROM words with your own. In fact, as you've mentioned the revised chr$ word, can you share it, it'll be interesting to see some string handling improvements.

Thanks Garth.
