\bc is the UNIX C compiler. _

\bc accepts several types of
Arguments whose names end with `.c' are taken to be C source
programs; they are compiled, and each object program is left
on the file whose name is that of the source with `.o' sub-
stituted for `.c'. The `.o' file is normally deleted, how-
ever, if a single C program is compiled and loaded all at
In the same way, arguments whose names end with `.s' are
taken to be assembly source programs and are assembled, pro-
