1. parsing a txt file
i am reading into my program a text file. in this text file i seek to
a certain line and assign 1 of my variables the value which happens to
be 20. however when i goto use this variable later i get a type check
failure saying the variable is {50,48,10}. I know this converts to 20
but i have forgotten how to convert it so that i can use it. can
someone please remind me. thanks

use
var = value(in)
in is your input, var will be a two-element sequence with the first element
being an error value and the second element being the number you are actually
interested in.
Refer to the library reference for value.

4. Re: parsing a txt file
{50, 48, 10} is equal to "20\n"
You need to do this:
sequence junk
junk = value( "20\n" )
myVar = junk[2]

Huh? not once did I mention stripping the line feed char off the string.
You don't need to get rid of excess chars... value("12345ABCDEF") will
return {success, 12345}

I do 1000's of pages of html per day of text extraction and parsing, and i have
no idea what you are talking about. How do you get sequence {50,48,10}
from an atom 20? If the one line is "20\r", i can see that happening. Why not
just grab the whole file and then use
parseddata = parse(data,{10,13})
or
parseddata = parse(data,{'\r','\n'})
? Then line one is parseddata[1], line 50 is parseddata[50], etc.

the file is an ascii txt file i am parsing. i am also trying not to
use any external libraries other than what i need because i want to be
in control of the speed. when i read in the file using gets i read the
entire thing in. if i print the file i get a seies of ascii keycodes.
if i puts the file i see it as it is in notepad. surely you know what
this is Kat??? , besides problem solved now anyway!
