The following assembler source file shows the usage of C Macros.

#if !defined (__AA__) || (__AA__ < 101)
#error "This source file requires AARM Assembler V1.01 or higher"
#endif

#pragma NOLIST
#include <91M55800.H> // Register file for Atmel AT91M55800
#pragma LIST

#define TEST1 10
#define MYTEXT "Hello World"

AREA    MYCODE, CODE
        MOV     R0,#TEST1 * 10

#if TEST1 == 10
        DB      MYTEXT
#endif

        DB      "GENERATED: ", __DATE__
END

The listing file generated by the assembler shows the text replacements performed by the C preprocessor:
