I am having trouble reading a text file and having it stay as text. I guess skill expects every text item to be quoted.Is there a way I can read it as text?
second choice: can I split each line into an Array?

Things of note:
1. The minus and plus sign in MODEM_48VIN- and MODEM_48VIN+ gets separated in the output, and that makes a list of two items: (MODEM_48VIN - TP30CIR_TOP)2. Program chokes on 48VIN- maybe because it starts with a number and ends with a minus sign.
Use gets instead of lineread:
(defun Read_String ()
FileData = infile("sample_infile.txt")
LocLine = parseString(str)
printf("%s %s %s\n" nth( 0 LocLine) nth( 1 LocLine) nth( 2 LocLine))
In reply to eDave:
Oops. Use this:
LocLine = parseString(str, " ")
That worked good except it seems to not exit gracefully from the While loop:

In reply to Geoff:
I found the problem. The text file had some empty lines at the end. Yes, I have to put a check for that.
Thanks for Your help Dave!
