C PreprocessorThe Ax51 Assembler includes a standard C preprocessor that is identical with the macro preprocessor in the Cx51 Compiler (with a few minor exceptions). The C preprocessor processes the source text of a source file before it is actually assembled. When the C preprocessor is enabled, C preprocessing is the first thing the assembler does. The purpose of the preprocessor is to replace or insert additional text into the source file just prior to assembly. Most of the obvious functions of the preprocessor require activation (by including preprocessor directives) in your source code. However, there are several things the preprocessor always does:
In addition to these operations, the C preprocessor supports the more obvious preprocessor operations:
Refer to the Preprocessor in the Cx51 Compiler User's Guide for more information about the preprocessor directives that are available. | ||||||||||
