As I said earlier, I have no idea how to use Euphoria very well. How to
input data from the user? Anyone wanna help me with some basic commands?
PLEASE?! If
you have ICQ, you can help. UIN: 6626887

Did you look at what you wrote before you pressed the Send button on your
e-mail? Your tone goes from desperate to demanding to insulting and rude -
not really a way to encourage people to respond. And you posted these things
at 11:00 Saturday night! Reality check time.
On one hand, you're asking for a basic guide to Euphoria, and on the other
you are rejecting ABGTE - something intended to provide exactly that
information. I've heard only good things about it - is there something in
particular about it that fails to meet your needs?
Your question is *too* open ended - could you be more specific as to what
*exactly* you are having trouble with? Perhaps a bit more background on your
problem would be helpful. For example:
- Is there a particular type of input you want from the user? A string of
characters, a number, or what?
- What have you tried to do, and where are you having trouble? Give example
code.
- Is there a particular command you don't understand, or some concept you
are having trouble with?
- Are you getting results that are unexpected?
- Are you getting results at all?
If you are trying to get input akin to a QBASIC INPUT command, you can try
this:
-- this will hold your input
sequence s
-- 'puts' is short for 'put string'
-- oops. make that 'put sequence'... 
-- this is akin to the print command.
-- the '1' specifies the output file as the screen
puts( 1, "What is your name? " )
-- 'gets' is short for 'get string'
-- or, 'get sequence...'
-- this is akin to the input command
-- the '0' specifies the input file is the keyboard
s = gets( 0 )
-- display the ASCII code of what the user entered:
-- the '?' is a sort of "raw" display function
? s
-- display the string the user typed
-- note the '&' is used to concatonate strings
puts( 1, "You typed: " & s )
Unlike QBASIC, gets() includes *everything* the user types. So if you did
this:
What is your name? Me
{77,101,10}
You typed: Me
The string is 3 bytes long:
77 = 'M'
101 = 'e'
10 = line feed
Here's a simple simulation of an INPUT statement:
function input( sequence prompt )
-- qbasic like input
sequence s
-- display prompt
put( 1, prompt & "? " )
-- get input
s = get( 0 )
-- remove the line feed
s = s[1..length(s)-1]
-- return trimmed result
return s
end function
If you want a simple user input function that handles the escape key and the
like, you can download "Simple User Input Routine" from
http://members.aol.com/FilesEu/exestuff.htm
As for a tutorial, try checking out a basic tutorial on 'C' - most of the
I/O functions have close analogs there. Just ignore all the pointer stuff -
Euphoria handles that much more elegantly.
Hope this helps!

So you get mad at me and then help me? Screw you and your little Mac PC demo

Maybe if you would not be so angry when you read posts, or then again when you
post, you would see that all David was trying to say was that your questions
were
too vague. Something like this one:
"Ok, I've learned to drive a car...how can I use that information to fly a
plane?"
Seriously, people on here are usually friendly, and you often get many answers
to
SPECIFIC questions. What you were saying with yours was "Ok, its late night
Saturday. I have nothing specific to say, so I'll just ask for help on Euphoria
in general. I'll then proceed to say ABGTE was crap, and maybe that'll inspire
someone to either write another tutorial, or even to be my mentor, and I'll pick
their brain for code at every step. When someone does return my posts, I say
'screw you' and hope they'll believe I was just kidding."
Basically, with the way you responded to David, it would be safe to say that
many
of your posts will be ignored in the future. My suggestion? Apologize. Move
on,
start asking more specific questions, and respond to anything politely. This
listserve is not the place for flamewars - go to some Usenet group if that is
what
you are looking for.

That's too gentle for "SonicGreen" attitude.... Can we expel him from the
listserver?
BTW SonicGreen, don't expect any help from me, now and in the future.

Yes, SG's response was short of desirable. I, being a Christian, like to
turn the other cheek on insults (although these were aimed at David Cuny), so I
tried the gracious route. Grace? Unmerited favor. But since SG has not since
responded I would assume his tirade was temporary, and that he has left us for
now.
Hehe, I never have anything good to contribute...gotta start writing some
programs!!
