I have experienced no corruption of data, but I certainly have had
unexpected behavior. Given:
put 1 into mcnt
repeat for each line tline in mlist
put empty into word 1 of tline
put tline into line mcnt of mlist
put mcnt + 1 into mcnt
end repeat
As each iteration of the repeat loop progresses I find the data I get
in tline is shifted to the right by the length of the deleted data.
I can only think an index is created at the start of the loop which
points to a memory location, and since the data is shifting while the
pointer does not, you must not change the contents of mlist until the
loop is finished.
So I learned when using this form to either store the contents of
mlist in a temporary variable and modify that, or build a temporary
variable as I go until the loop is complete. Then I put the contents
of that variable into mlist if that's what I want.
I have had no problems changing the contents of tline.

I want to use the 'for each' form of the repeat loop, but don't
know how
to use it to modify data within a container. For example:
repeat for each line thisLine in vContainer
put doSomeFunction(item -2 of thisLine) into item -2 of thisLine
--how do I get the change back into vContainer?
end repeat
Thanks!
