Jerome's post in connection with this put me in mind of a BASIC package 
written by an old (I lost track of him a long time ago) friend, Mike 
Louder--Prime Factor BASIC.  Stil have the disk and manual on the shelf, 
even though I've ever owned an Apple II.  I think it qualifies as 
"languages no longer in use".

Does arbitrary-precision modular math--used in some early crypto work. 
Has anyone other than myself ever heard of this package?
