Trigger Problem - Signature Error Service Program

I recently has a problem in a trigger programme which resulted in an
RNX1024 message , which basically does not tell you very much other that
the fact the an error occurred. After 3 days I finally realised that it
was a signature error with a service programme. With non trigger
programmes such an error is pretty visible with messages in the log etc
and thus relatively easy to rectify. Is there a technique for improving
the diagnostic information provided when a trigger programme falls over
? Compile time option for example 

 

Thanks in advance
