Talk:IBM Peterlee Relational Test Vehicle

Hi. In the third bullet point, what do 1993 and 1996 refer to? Thanks! Sam Staton 20:00, 13 February 2007 (UTC)

MP/3 - where did it come from, where did it go?
MP/3 (Macroprocessor/3) was the brainchild of Salah Mandil, an IBM Research Fellow (if memory serves). Reminiscent of the C Preprocessor, it was a REPL permitting fast online interactive development and immediate testing of additional macros, after the manner of "del"-function definition in APL. It was used by PRTV to provide a soft top-end (UI) to the cumbersome ISBL command language (also a REPL) which drove PRTV. Which means it must have been shipped as part of UMS (Urban Management System) which was based on a hacked-about PRTV, though I can't claim to know that for sure. Salah's "killer app" written in MP/3 was a symbolic differentiator, which handled all the calculus I could ever think of. If it didn't, Salah would add another couple of macros. When Peterlee Scientific Centre was moved down to Winchester in 1979, I lost track of Salah - does anyone know what became of him? I know of no subsequent use of MP/3 – maybe someone else does?
