RE: Change Invisibles: migrating from Xy 3.55 to 4.017 (should be 4.018)

[Peter Brown pbrown@xxxxxxxx]

Many, many thanks, Carl :-). Those changes seemed to do the trick, at least
on my very short test file. Now the trick is to figure out from Robert's
ctrlchar.txt how to do the search and replaces on hundreds of [BC] and [XC]
functions in the program files, or else change 'em by hand, then re-debug
the program. Aaarrgh! No such thing as a simple upgrade.

The first thing I'd do is force the display into eXPanded view (func XP)
before executing CI. Xy4 is optimized for speed in eXPanded view (unlike
XyWin, which runs faster in graphics view).

Next I'd change every instance of BC to BX and every corresponding XC to Q2.

Blind execution of commands works a dramatic speed increase in most
programs.

Finally, if you haven't already done so, turn on Error Suppression at the
beginning of your routine: BX es 1Q2.
