no-op /noh'op/ /n.,v./ alt. NOP /nop/ [no operation]
1. A machine instruction that does nothing (sometimes used in
assembler-level programming as filler for data or patch areas, or
to overwrite code to be removed in binaries). See also JFCL.
2. A person who contributes nothing to a project, or has nothing
going on upstairs, or both. As in "He's a no-op." 3. Any
operation or sequence of operations with no effect, such as
circling the block without finding a parking space, or putting
money into a vending machine and having it fall immediately into
the coin-return box, or asking someone for help and being told to
go away. "Oh, well, that was a no-op." Hot-and-sour soup (see
great-wall) that is insufficiently either is `no-op soup';
so is wonton soup if everybody else is having hot-and-sour.
