Syntax:
else
The else directive marks an optional clause of a conditional-compilation block defined by a ifdef, ifndef, or if directive. The else directive must be the last directive before the endif directive.
This directive has no arguments.
Example
This example compiles the second BITMAP statement only if the name "DEBUG" is not defined.
#ifdef DEBUG BITMAP 1 errbox.bmp #else BITMAP 1 userbox.bmp #endif
