code 1. 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 operates on. Among hackers this is a mass noun, as in How much does it take to do a bubble sort ? , or The is loaded at the high end of RAM. Among scientific programmers it is sometimes a count noun equilvalent to program ; thus they may speak of codes in the plural. Anyone referring to software as the softwares is probably a newbie or a suit. 2. v. To write. In this sense, always refers to source rather than compiled. I d an Emacs clone in two hours! This verb is a bit of a cultural marker associated with the Unix and minicomputer traditions (and lately Linux); people within that culture prefer v. to v. program whereas outside it the reverse is normally true.
