Summary: We begin to consider how you can write your own procedures and why you might do so.
their own procedures, we mean collections of Scheme commands that are parameterized and referred to be a single name, just like the built-in procedures, such as
open jarprocedure changes the state of the jar
image-fill!adds virtual paint to an image.
(define your-procedure (lambda (param1 ... paramn) expression1 ... expressionm))
(define square (lambda (val) (* val val)))
I usually create these pages
on the fly, which means that I rarely
proofread them and they may contain bad grammar and incorrect details.
It also means that I tend to update them regularly (see the history for
more details). Feel free to contact me with any suggestions for changes.
