On more quickie regarding 'functions':  I've got these integrated into a
curriculum outline here:  http://www.4dsolutions.net/ocn/mainoutline.html
You'll see it's pretty traditional, but the context is clearly influenced by
computer science.  I haven't touched this document since Oct 9, 2003 but
still consider it current enough to be useful in the field.
