If I don't use the conditional and just comment out the interupt option I don't want, it compiles/assembles correctly. I have conditionals burried in the interupt load file and that is working correctly.

I find it very confusing and odd that the syntax for these directives starts with the ' comment delimiter. Does that mean these lines can't be commented-out?? Using '' <-- that's two ' does not seem to work; the conditional compile is taken regardless. And, I must admit that I'm curious about the reason for implementing these this way. example: '{$DEFINE Bluetooth} 'compile Bluetooth code if defined (true) ''{$DEFINE COMport} 'compile serial port I/O if defined (true) '{$DEFINE EnFilter} 'enable digital filtering of sample data ''{$DEFINE DebugMode} 'compile debug statements if defined (true) ''{$DEFINE DualAxis} I could see changing DEFINE to unDEFINE, but it gets more difficult if I want to comment out the IFDEF...ELSE...ENDIF's Got any helpful guidance?

I use conditional compile directives a lot for feature options. This ' comment delimter in the SX/B directive syntax is creating an annoyance for the porting of other code. ...and I can forsee it causing possible future difficulty.

Today for example, I finally spotted '{$IF ... } instead of '{$IFDEF ... } and '{$IF ... } appears as a comment to the SX/B compiler so it fails to generate a syntax error!?

Yes, conditional directives look like comments, deliberately, even if the process is imperfect, it works. Many of use use SX/B day-in-and-day out in our professional lives; I don't have problems with conditional directives and I use them in almost every program I generate. Learn to use them correctly instead of focusing on what you could [deliberately] do incorrectly.
