This is the utility I've been working on that had me posting on here for
help from time to time. I enjoy programming in scheme probably more then CL
because of its simplicity, but I wanted to check out and go through some
common lisp books like Practical Common Lisp(which is awesome). But I find

Hello,
I am running Racket 5.0.1 in Windows.
Specifically, I'm using racket.exe from the Windows cmd prompt.
If I enter a multi-line expression manually, it works fine:

6
But if I copy and paste in the same expression, I get an error:

Hi everyone,
I wanted to double check things before I start re-hacking the WeScheme

Thanks much. Would you like me to do a diff and commit those c
reading on scrtachbox it seems to cross compile for specifically for
embedded linux - is iOS based on linux?

I once used scratchbox to cross compile mzscheme to arm

The Maemo SDK is based around the Debian-oriented Scratchbox Cross

I've been struggling for a while to find out how to

For example, suppose you want to define a macro that takes

I've just put up a new version of the package with your change.

It is probably better to use command-line (what Jay pointed to) and,
if you do, you can pass the #:argv argument to like Eli suggests.

If so, to develop the program, open the language dialog in DrRacket (cmd L) and
ask for details.
In the text box for "command line arguments ..." enter some strings between the
parentheses, like this:
#("hello" "1" "#t")
and click OK
In the definitions window, enter

Sorry, there isn't a way to do that at the moment.
But it occurs to me that when Stevie is done with the chaperone
overhaul of the contract system then equal? will do what you want (so
you can use hashes for your metadata).

I'm continuing with define/contract a bit. Let's say there are two
definitions like this
#lang racket
(define/contract (sum/c lon)
((listof number?) . -> . number?)
(sum lon))
(define (sum lon)
(if (empty? lon)

(+ (first lon)
(sum (rest lon)

I know many programs that accept input while calling the program like:
"program -o option" I'd really like to use this for my next few projects but
I'm not even really sure where to even look for information. I've been
scouring the racket I/O docs and even the r6rs docs, but haven't found
anything

Dave, do you have any suspicions about how far the webserver has moved
compared to where the xmlrpc library is? I simply haven't used Scheme

Dear Racket list,
As a non-expert of Scheme macro system,
I've been struggling for a while to find out how to
define a macro that can take a procedure as argument.
For example, suppose you want to define a macro that takes
an identifier and an expression, modifies the identifier in some
way, and
