r5rs

Background: I am new to scheme, and am using DrScheme to write my programs.

The following program outputs 12345 when I run the program as r5rs:

However the following program outputs nothing (it's an r6rs program):

#!r6rs
(import (rnrs))

12345

That being said, I can get it to output 12345 by doing this:

#!r6rs
(import (rnrs))

(display 1235)

Is that something new with r6rs, where output only occurs when specifically specified using display? Or am I just doing something else wrong

Does R6RS or Chez Scheme v7.9.4 have a library function to check if a list contains duplicate elements? Alternatively, do either have any built in functionality for sets (which dis-allow duplicate elements)? So far, I've only been able to find an example here. The problem with that is that it doesn't… >>> More

What is the standard way to throw and catch exceptions in R6RS Scheme? I'm looking for syntax that works in any version of Scheme (not just PLT) that implements R6RS. R6RS guard syntax looks like it might fit the bill, but can somebody show me an example of how to actually use it? >>> More
