Hi Peter,
After looking more into the issue, it appears that you have been
exploiting a bug in LiveCode 6.7 for a long time, that's not a bug in
LiveCode 7.0 :)
If you change
by NULL
with
by ";"
then you will have the same thing in 6.7 as you see with NULL in 7.0:
the behaviour described in the documentation.
I suggest you to get a look at the bug report
(http://quality.runrev.com/show_bug.cgi?id=15641) for more explanations.
Regards,
Sébastien

Moreover, that example succeeds in LC 7!

A heads up:
split tText by cr and null
works differently in LiveCode 7 than it did in LC 6. The cr parameter is
OK, but the null adds another cr when this expression is used in LC 7.
I am trying to understand what the intent is/was of using "and null" as
it seems to be functionally irrelevant in the example stack. i.e. 'split
tText by cr' and 'split tText by cr and null' produce identical results
in LC6
the 'and null' would only be relevant in the split command if you had
array keys separated from array values by nulls in your data (example
below) and using a null as a delimiter seem odd
put "A"&null&"apple"&cr&"B&null&"bottle"&cr&"C"&null"&"cradle"&cr into
myVariable
split myVariable by cr and null
to presumably get
array[ A ]=apple
array[ B ]=bottle
array[ C ]=cradle
However, the statements above fail in Livecode 6 in that the output you
get is:
array[ 1 ]=A apple
array[ 2 ]=B bottle
array[ 3 ]=C cradle
where the "white space" between A and apple is a null, split fails to do
anything with a null delimiter in LC6 (tested in LC6.7.5)
For data that is just:
Line 1
Line 2
Line 3
the proper syntax seems like it should just be 'split tText by cr'
