   SYS$IMGSTA is set as the program transfer address ahead of your actual   
   program transfer address unless you do LINK/NODEBUG, as I recall.   
   Without this option, the linker includes source line-number   
   information, but not full debug symbol tables.   
      
   If you do RUN/DEBUG, then SYS$IMGSTA detects this and starts up the   
   debugger instead of your actual mainline. If /DEBUG is not specified   
   on RUN, then it goes to your actual mainline.   
      
   With LINK/DEBUG, I think you get full debugger symbols in your image,   
   and a flag setting that tells SYS$IMGSTA to always go to the debugger   
   (unless you do RUN/NODEBUG? I think that was it.)
