Conditional CompilationConditional compilation directives allow you to designate parts of the program for the compiler to ignore. These parts are not compiled and no object code is generated for them. Conditional directives resemble the C if statement and may be used to test defined macros or arithmetic expressions. The test performed by a conditional directive is done at compile-time by the compiler. Depending on the result of the test, source code is either included or excluded from the compilation. There are several reasons to use conditional compilation in your program.
Following is a list of the available conditional compilation directives.
