Writeline Limitations

I have a project where I must create a single-line upload file. Through testing it appears KiX is limited to 31,999 characters that can be written on a single line. My question, does anyone know if such a write process truly writes 31,999 characters on a single line? I script w/Notepad, and its limits of 1024-characters makes it appear that the file has 32 lines (using GOTO Line brings me to additional lines). My guess is the process writes properly as a single line, but I've no other tools to verify.
Can anyone help me with this? I'd appreciate it.
Bill
My simple test script:
code:
$Fil = "C:\Temp\wl.txt"
$Idx=0
$Chk=31999
$Char=A
OPEN (1, $Fil, 5)
DO
$Char=$Char + "A"
$Idx=$Idx+1
? "Idx: $Idx"
UNTIL ($Idx = $Chk)
$wri = writeline (1, "$Char" + @CRLF)
CLOSE (1)

UltraEdit can show your file. I have version 8.10b. It displays a text line of 31,999 "x"'s as multiple lines of ~4,095 chars (max length) but does not increment the line numbers until the next line (CRLF) is encountered.

Using UltraEdit v10.0b I get the following results.
7 Columns of 4200 A characters
1 Column of 2600 A characters
for a total of 32,000 characters (0 idx starts the count)
KiXtart v4.12 used for testing.
Modifying code from 31999 to 32000 returns error
quote:
Idx: 31998
Idx: 31999
Idx: 32000Script error: expression too long!
$wri = writeline (1, "$Char" + @CRLF)
Using KiXtart v4.21-RC2 I get the following result
quote:
Idx: 31998
Idx: 31999
Idx: 32000
ERROR : expression too long!
Script: C:\SCRIPTS\test.kix
Line : 14

And this example will create a 50,000 character "line".
$sFile="C:\Temp\wl.txt"
; Construct 10,000 character string.
$sSpace10=" "
For $iIndex=1 To 1000
$sSpace10000=$sSpace10000+$sSpace10
Next
$nul=Open(1,$sFile,5)
$nul=Writeline(1,$sSpace10000+$sSpace10000+$sSpace10000+$sSpace10000+$sSpace10000)
$nul=Close(1)

Using FOR/NEXT I still ran into limitations as well. However, a programmer friend suggested the following simple change - remove the line feed for each write - and I easily wrote 100,000 characters to a line. Downloaded UltraEdit and it saw as 1 line, 100,000 characters. Logic for my script is to not use CRLF with any write. Duh!

code:
$Fil = "C:\Temp\wl.txt"
$Char=A
OPEN (1, $Fil, 5)
FOR $Idx=1 to 100000
$wri = writeline (1, "$Char")
NEXT
CLOSE (1)
