1. /aws/ (East Coast), /ay-os/ (West Coast) A
PDP-10 instruction that took any memory location and added 1 to it. AOS meant "Add One and do not Skip". Why, you may ask, does the "S" stand for "do not Skip" rather than for "Skip"? Ah, here was a
Beloved piece of PDP-10 folklore. There were eight such instructions: AOSE added 1 and then skipped the next instruction if the result was Equal to zero AOSG added 1 and then skipped if the result was Greater than 0 AOSN added 1 and then skipped if the result was Not 0 AOSA added 1 and then skipped Always and so on. Just plain AOS didn' t say when to skip, so it never skipped. For similar reasons, AOJ meant "Add One and do not Jump". Even more
Bizarre, SKIP meant "do not SKIP"! If you wanted to skip the next instruction, you had to say "SKIPA". Likewise, JUMP meant "do not JUMP" the unconditional form was JUMPA. However, hackers never did this.
By some quirk of the 10' s design, the
JRST (Jump and ReSTore flag with no flag specified) was actually faster and so was invaria
Bly used. Such were the perverse mysteries of assem
Bler programming. 2. /A-O-S/ or /A-os/ A
Multics-derived
operating system supported at one time
By
Data General. A spoof of the standard AOS system chefistrator' s manual ("How to Load and Generate your AOS System") was created, issued a part num
Ber, and circulated as photocopy folklore it was called "How to Goad and Levitate your CHAOS System". 3. Alge
Braic Operating System, in reference to those calculators which use
infix operators instead of {postfix notation}. [
