= C =
The stuff that software writers write, either
in source form or after translation by a compiler or assembler.
Often used in opposition to "data", which is the stuff that code
operates on. This is a mass noun, as in "How much code does it
take to do a bubble sort?", or "The code is loaded at the
high end of RAM." Anyone referring to software as "the software
codes" is probably a newbie or a suit.
