IIRC,

1. When I tried saving defined text to 05, it didn't work
(this may have been with a version prior to 3.55, it was
certainly a long time ago).

2. Somewhere along the line I came across an advice from
XyQuest to use any variable from 0 - 9 (not 00 - 09).

Thanks Carl, but I don't run selected code very often ..

Nice to know.
