I need to convert some Lisp programs to Scheme. Is there a conversion
program, some tools that will make it easy?

Thanks

Vlad

Your mind.

> some tools that will make it easy?

A healthy brain and a good editor. If they are large CL programs,
you're in for a _lot_ of work. If they are small, it shouldn't be too
hard as long as there aren't too many CLisms like LOOP. Expanding some
of CL's trickier macros like LOOP might give you hints on converting
the code. It would be easier to convert Scheme to Lisp, barring a few
nice Scheme features like continuations.

  is this for human or compiler consumption?

  the ultimate conversion program is an implementation of Common Lisp in
  Scheme.  however, since Scheme can easily be implemented in Common Lisp,
  and has been some twenty million times, perhaps you'd rather want to
  stuff your Scheme code into a real Lisp?

From the doc (I haven't tried it), this looks to do it the other
way around--scheme to cl, same as jonathan rees's pseudoscheme.

Well, properly Rees's system is mostly to allow Scheme programs
to run under CL.  It does actually translate them, but hides
the translation mostly.

oops, sorry!
couldn't even imagine any use for the other way 'round :)
