Does anyone know or use the Mr. Ed or Pretty Big portion of Dr Scheme? I have been fooling around with the language for about three months, and after a one month dry stretch, I seem to have forgotten how to use sub routines. Can someone please help me?

P.S. This is my first post, and I know a bit about the Mr. Ed. part of Dr Scheme, but I do not know if it is possible and if possible how to use scheme subroutines. In all of the languages I use, sub routines are my best buddy! :mrgreen:

If anyone does use Dr Scheme, I am working on a scheme project. PM or email me for details.
