Handling an abort in karel

  • I'm working on my first karel program, a pretty basic data logger. My basic idea is like this:


    Existing karel program reads bar code and calls appropriate PNS program
    PNS program runs my datalogger
    datalogger starts a cycle timer and grabs barcode data from existing karel program
    datalogger waits on semaphore from TP production program
    PNS program calls production program
    production program does it's thing
    production program ends and sets semaphore
    datalogger stops cycle timer, grabs the value of a half dozen or so registers, writes timestamped entry to log file


    I've figured out how to do all this (although if there's a better way I'll take any suggestions anyone has), my problem is how to deal with an abort between when the datalogger starts and the production program ends? I still want to log the attempt at production including all the register values as well as what triggered the abort (eg; condition handler, FNCT > Abort (all), limit error) but I'm not sure how to set up a listener for this.
