It confused me too, several times even. For decoding the encoding menu, bit
0 has to be set, which means that bit 0 must be 1. For decoding the font
menu, you should therefore enter 0 here, as Martin stated already.

Good question. I've now updated the block% with the given entries and
terminated it with -1, before passing it to the above call. This works
indeed, hallelujah! Thank you very much.

The only question is, why didn't I have to do the same in the other
program? Presumably, because that program is much more simple, so that the
block% arrived unchanged from poll to call - contrary to the current mess.

Again, a piece is added to the wimp jigsaw.
The news groups are great.

Kind regards,
