C251 User's Guide
The C251 Compiler User's Guide contains information about how to
use the Keil C251 Compiler. The C251 Compiler creates object modules
from the C files you write and compile. Object modules created may be
added into a library (using the LIB251 Library Manager) or may be
linked with other object modules and libraries to form a program
(using the L251
This manual contains the following topics:
