IFP [1] is a variant of Backus' FP [2] language.  The IFP interpreter is an 
order of magnitude faster than the fp that comes with BSD 4.2.  The interpreter 
is written in C and runs on every UNIX box I've found.

I'm going to try to make the IFP 0.5 sources available (probably by 
anonymous ftp.)  Those that are interested should send me e-mail.
I'll also make an MS-DOS version for IBM-PC clones available.
