Just use constants instead of the macro. There's also .IFREF, which checks if the source up to the point where .IFREF was used has any references to a specific symbol. This can be used to build subroutine libraries that are assembled only if they have been referenced before. As a sidenote: It has been a bad decision to use .DEFINE for a special macro style since many people think they're really C style macros and use them as such. They're not, and doing so will fail in many places.
