It's not STk-specific, but something that might be very helpful is the
chapter on porting from Tk 3 to Tk 4 in Brent Welch's book, "Practical
Programming in Tcl and Tk". You can find out more about the book at
<>--plus, the chapter
itself (along with some Tk 4 changes that didn't make it in before the
book went to press) is duplicated in a link off that page.

Most (not all) of the STk changes I've found are more-or-less directly
related to changes in Tk.

Yeah, & isn't defined in STk 3. It was a function that basically
concatenated print prepresentations of all its arguments together into
a string. Probably the simplest way to solve this problem is to
define & before you load anything--you can find it in tk-init.stk in an
STk 2 distribution.

I've got a fairly large application (mostly written with stklos) mostly
ported. Unfortunately I didn't keep organized notes on what I had to
change, but I'd be happy to try to help with specific problems.
