NPL
1. New Programming Language. IBM' S original (temporary) name for PL/I, changed due to conflict with England' S "National Phy Sical Laboratory." MPL and MPPL were con Sidered before Settling on PL/I. Sammet 1969, p.542. 2. A functional language with pattern matching de Signed by Rod Bur Stall and John Darlington in 1977. The language allowed certain Set S and logic con Struct S to appear on the right hand Side of definition S, E.g. Setofeven(X) <= <:x: x in X & even(x) :> The NPL interpreter evaluate S the li St of generatorS from left to right So condition S can mention any bound variable S that occur to their left. The Se were known a S { Set comprehen Sion} S. NPL eventually evolved into {Hope} but lo St Set comprehen Sion S which were called liSt comprehenSionS in later functional language S.
