I'm improving a program that launches another program with a parameter. =
I
use a function to prompt for a parameter. The external program's
parameters are strictly integers (the parameter of the track of the CD yo=
u
want to play).
I discovered that if I enter 7, Euphoria passes on ASCII 7 to the program=
,
which doesn't make sense of course. If I type '7' at my prompt the
program, as I expected, plays track 7. Well, I don't want to type the
quotes. I just want to type say 7 and have Euphoria pass on '7', how do =
I
remedy this?

Have you tried creating a string file with the '#' s as values and then
doing a gets() ?
This should give you what you need.
Respectfully,
Robert
P.S. If I'm wrong please let me know. :)

include get.e
sequence s
atom i
puts(1,"Track:")
s = gets(0)
s = value(s) -- convert string into a 2-element sequence
i = s[2] -- s[1] is GET_SUCCESS/FAILURE
-- s[2] is the numeric value you typed.

Oops! I mis-read the question. Sorry.
The method below will write a single byte to a disk file, 0 to 255,
which should be enough to select any CD track!
include get.e
sequence s
atom fn
atom i
puts(1,"Track:")
s = gets(0)
s = value(s) -- convert to an integer value
i = s[2] -- discard the GET_SUCCESS...
fn = open("TEST.NNN","w")
puts(fn,i) -- write the byte to disk
close(fn)
fn = open("TEST.NNN","r")
i = getc(fn) -- read one character from the disk as an integer
printf(1,"I is %d",i)
close(fn)
Hope this helps,

Irv,
I just read your latest post. Do I really have to create another file? =
Here's the algorithm I'd like to use.
1. input integer.
2. Convert to ASCII sequence.
3. system command line & space & ascii sequence.
Can Euphoria do that? (G)

6. Re: Inputting Something without ''
maybe I'm misreading, but this sounds like a job for sprintf(), not
value(), to translate before passing the input on.

sequence track
sequence cmd
-- assume I enter a 7 each time (no quotes):
track = gets(0) -- this creates COMMAND 7
cmd = sprintf("COMMAND %s",track)
puts(1,cmd)
track = gets(0) -- this creates COMMAND 55
cmd = sprintf("COMMAND %d",track)
puts(1,cmd)
Does either of these do what you want?

Sounds like you are using get(). Try using gets() instead. get() is
reading 7 as 7, and returning the number 7. When you give get() '7', it
takes the ASCII value of the character 7 and returns it. gets()
automatically returns a sequence that contains the ASCII values of what
you entered. (Which is what you want.)
sequence test
puts(1, "Enter in track number: ")
test = gets(0)
test = test[1..length(test)-1]
-- If you entered 7, then test will contain: {'7'}, or "7". This sounds
like
-- what you want.

Boy, how one letter can make a different. I belive I was using get,
instead of gets. Thanks.
