From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  AOS
       
          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 invariably used.
          Such were the perverse mysteries of assembler 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 administrator's manual
          ("How to Load and Generate your AOS System") was created,
          issued a part number, and circulated as photocopy folklore; it
          was called "How to Goad and Levitate your CHAOS System".
       
          3. Algebraic Operating System, in reference to those
          calculators which use {infix} {operators} instead of {postfix
          notation}.
