[by analogy with `append'] To
prefix. As with `append' (but not `prefix' or `suffix' as a
verb), the direct object is always the thing being added and not
the original word (or character string, or whatever). "If you
prepend a semicolon to the line, the translation routine will pass
it through unaltered."
accumulator n. obs.
1. Archaic term for a register. On-line
use of it as a synonym for `register' is a fairly reliable
indication that the user has been around for quite a while and/or
that the architecture under discussion is quite old....
