* POO (pooh, as in Winnie-the-) n. Principles Of Operations. See POP. This acronym was used extensively in FSD (Federal Systems Division) and elsewhere in the late 1960s and early 1970s but is less often heard since then − probably because so few now write programs in assembler. Also mini-poo for the green card. * POP, POOP, POPs, p.ops (pops) n. The manual that defines the principles of operation of the System/360 (and, later, the System/370). Probably the best (most rigorous) data processing architecture document ever written, and the source of the Ultimate Truth for many. See also bible, POO, Princ Ops * Princ Ops (prince-ops) n. A verbal abbreviation for the System/360 (and later extensions) Principles of Operations Manual. Used by the System Architecture group in Poughkeepsie, and others. See also POO, POP. My conclusion is that the issue hasn't changed much in 20 years, and apparently long before. Note the comment about "..few now write...". Hard to say if he meant that seriously or not. If interested in the dictionary, just google the title, it seems to be widely available. sas
