This loop should give you eveything you're looking for - handles null (zero byte) files like a charm ...

code:

---

BREAK ON

$CHK = ""

$logfile = "C:\RC.TXT"

$ = OPEN(1,$logfile,2)
IF @error = 0
 $x = readline(1)
 while @error = 0
  if instr($x,"rtvscan.exe")
    $CHK = "Running"
  endif
  $x = readline(1)
 LOOP
 $ = CLOSE(1)
ENDIF

?"CHK=$CHK"

EXIT 1
