COMPATIBILITY
From another C compiler to this C compiler
• Modification is not required if the keyword bit, boolean, or _ _boolean is not used.
• When changing variables to bit or boolean type variables, modify the program according to the method
above.
From this C compiler to another C compiler
• #define must be used. For details, see 11.6 Modifications of C Source (As a result of this modification,
the bit or boolean type variables are handled as ordinary variables.).
