This code works as written under Win_vista32, that is pausing if the files does not exist or of the current line does not exist.

but instead it automatically increments under Win_xp and %line% seems to have valid data.

Why? The purpose of the scripts is proof of concept of interprocess communication across computers. (yes I know of wm_messages for the same computer)

the first script reads a file looking for new lines
if there is no line I get the text that includes _____ underscores

Code:
#singleinstance force
#Persistent

;reader
CoordMode, ToolTip, screen
CoordMode, Mouse, screen


filename=tester1.txt

x=600
y=400
b_index=1

loop
{
 FileReadLine, line, %filename%, %b_index%

 b_errorlevel:=errorlevel ; so I can see the value using listvars
;listvars
;msgbox
 if b_errorlevel = 0
 {
    tooltip, %b_index%:%line% , x, y , 1
    b_index++
 }
 else
    tooltip, %b_index%:__________ , x, y , 1

  sleep, 200
}
return

+esc::exitapp


f12::reload

the 2nd script appends a line to the file that the 1st reads
Code:
#singleinstance force
#Persistent

; writer
CoordMode, ToolTip, screen
CoordMode, Mouse, screen
b_index=1

filename=tester1.txt

x=600
y=400
b_index=1

settimer, fred, 200

return

fred:
mousegetpos, x, y
Fileappend, test%b_index% x%x% Y%Y%`n, %filename%
b_index++
return

loop
{
Fileappend, test%a_index%`n, %filename%
  sleep, 200
}
return

^esc::exitapp

f11::reload

Have you seen this? Might be easier.

With regard to your script, I am not sure what you are trying to do, or why it is a problem?

I want to read a specific line # from a file, and if that specific line is non-existent, be informed via errorlevel as specified in FileReadLine.

This notification seems to work in Vista-32 but not in my case Win-xp.

I am looking for confirmation of same results or conflicting results.
Or phaps I have an error in my script that I can not see.
