first check the size of the split array by using the UBOUND() command, that would prevent you from trying to pull an nonexistent array field.

code:

break on
$logfile = "D:\TEST.DAT" <-- change this
if open(1,$logfile,2) = 0
 $line = readline(1)
 while @error = 0
  $array = split($line,",")
  if ubound($array) < 2
    ;don't pull the array info! kix will crash!
  else
    ?"Third element = " $array[2]
  endif
  $line = readline(1)
 loop
 $ = close(1)
endif
exit 1
