Symbolic Value : Resource Definition
helptext - Assign an error code number to a text string.
Symbolic Values :
Assigns the given error code to the given text string. When language compiling, the macro actually amounts to nothing more than a comment. When resource compiling a module (RC), the macro is used to map error code numbers to a corresponding text string.
Prior to Release 4.5, an alternative form was defined due to a compiler bug in MPW C. The compiler generated an error when a macro evaluated to nothing and is followed by another #define.
