code n.
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.
