Curious additions to this puzzle:
Negative indices don't help: In a 4004-segment string, using an index of -1,
-2, etc. doesn't work until you
reach an index corresponding to something that would work with a positive index.
But stringSegmentCount() remains accurate way past 4000 segments.
This 4000-segment limit sounds vaguely familiar though I don't remember why.

you are right. Paul B

Hi All,
I have a script to read a text file into a string variable, and then to be
able to address each line in it, by using the lineFeed character backslashN
as the delimiter in a StringSegment statement.
It works quite well, until segment 3999.?? Segment 4000 then contains all the
remaining segments, and any request for a segment higher than 4000 returns
only a nul string.
I thought it may have been because of the non standard backslashN delimiter,
so I used the below script to test the StringSegment function, using the
standard LIST_ITEM_SEPARATOR, and the function repeatedly fails at segment
4000, regardless of each segments size, and which delimiter is used.
Has anyone encountered this???
Could someone please look at the below test script, and let me know if, when
you enter a line number higher than 3999, whether you get a sensible result,
and if so, what my problem may be?
Note, entering a line number into the input box should read the segment for
that number, and pressing escape escapes the while loop.
Script Test () ; F8
var
int?? iCount,
string?? sChoice,
string?? sText
For iCount = 1 to 5000
let sText = sText + IntToString (iCount) + " ABC DEF GHI JKL MNOP QURS TUV
WXY Z " + LIST_ITEM_SEPARATOR
endFor
WHILE InputBox ("line", "?? ", sChoice)
let iCount = StringToInt (sChoice)
SayString (StringSegment (sText, LIST_ITEM_SEPARATOR, iCount))
EndWhile
EndScript
With appreciation,
Paul from Australia
