Doc,

You're right - readline() returns a chr(0) when reading empty files (and I was using RC3 in my testing) ... would this be a suitable work-around (given that your reading a text file - should be no CHR(0)'s in there ?) :

code:

BREAK ON
$CHK = ""
$logfile = "C:\RC.TXT"
$ = OPEN(1,$logfile,2)
IF @error = 0
 $x = readline(1)
 ?"@ERROR"
 while @error = 0 and $x <> CHR(0)
  if instr($x,"rtvscan.exe")
    $CHK = "Running"
  endif
  $x = readline(1)
 LOOP
 $ = CLOSE(1)
ENDIF
?"CHK=$CHK"
EXIT 1

Or maybe, when you create the RC.TXT file, you can throw in an extra byte or two at the end (guarantee at least two in the file) and avoid this prob. altogether - say, by echo/appending some extra chars ?
