Thanks for that explanation Bruce!

Here's a line from my ARB script that causes such an error:
; Local TempScrData, CmdLine, CRLF, TempScrPath, TempScrName
; TempScrData = Repeat("!", 290)
; --- all one line below
TempScrData = TempScrData ++ ?'Esc(?"' ++ ReplaceChars(ReplaceChars(CmdLine, ?"\",
?"\\"), ?'"', ?"\X22") ++ ?'", ?"\") ++ CRLF ++ Tab ++ ?"Quit" ++ CRLF ++ ?"; " ++
Repeat(?"_", 70) ++ CRLF, ?"A")' ++ CRLF ++ ?'Event.Create(5, 0,
?|File.DeleteNoRecycle(?"' ++ TempScrPath ++ ?'")| ++ CRLF ++ ?|If(Not(ValidPath("' ++
TempScrPath ++ ?'")))| ++ CRLF ++ ?"Event.DestroyThis")' ++ CRLF ++ ?"Else" ++ CRLF ++
?'Event.CreateMS(100, 1, ?"' ++ TempScrName ++ ?'")' ++ CRLF ++ ?"EndIf"
; --- all one line above
One observation that may be of interest is that if you place this line
into a blank script and run it, you won't see an error. I believe that
this is because of the length of TempScrData being at least 290 bytes
in length before this command is reached.
The fact that most of this line (besides the ReplaceChars() part)
consists purely of ?"just strings" ++ Vars ++ ?"more strings" ++ etc.
also points at the string's initial length as the culprit.
