Replaces a designated constant or macro name in the program with a designated character string.

#define <Symbol constant> <Character string>

or

#define <Macro name (Argument)> <Argument included character string>

This statement replaces <Symbol constant> or <Macro name> in the program with a designated character string. In the case of a macro name, it is replaced with the arguments already included.

<Symbol constant> or character strings of <Macro name> in " " (double quotations) are not replaced.

You must describe the #define statement on one line.

You must place 1 or more space characters between <Symbol constant> and <Character string>.

Do not place a space between a macro name and the parentheses of an argument.

You can redefine <Symbol constant> and <Macro name>, however, you need to make them invalid with #undef at least once. The most recently defined ones become valid.

<Symbol constant> and <Macro name> must be within 64 characters.

You can use a maximum of 2048 macro names in one program. There is no limitation to the number of macro function arguments you may use.
