I was sort of burning out or something by Phil Crowe's simple assembly talk. I didn't take any notes at the time. I had intended to go to mjd's conference presentation judo talk, but I was delighted by what I heard. PAL is a simple assembly interpreter with a small instruction set. It was neat because it was constructed as a teaching tool. Each line is read and built up into a string to be eval'ed. Nice approach, much easier than trying to emulate a byte machine. The code is available as assembly-0.21.plt from the scripts section of CPAN. Nice job, Phil. You've got lucky students.
