:Tool Chest:Testing & Debugging:Debuggers & dcmds:MacsBug 6.5.2

2) Create a file using ResEdit (or Resorcerer, etc.) containing a 'mxbm' resource (the 'mxbm' resource contains macro definitions).
3) In this 'mxbm' resource, define the macro 'everytime' as follows:
stdloginto 'Send to the programmer'
This way, if MacsBug is ever invoked due to a program error, you will automatically get a log of what occurred. The log, named "Send to the programmer" will exist on the desktop.
4) Have your customer send you the log file created by the above steps.
