Hi,

formerly I used ReferenceStream, SmartReferenceStream. Format is binary 
and not necessary compatible over image versions.

readTrainingsSamples
     "read the class var TrainingsSamples from a file using 
ReferenceStreams "
     | rr |
     rr := ReferenceStream fileNamed: 'trainingssamples.obj'.
     TrainingsSamplesFehlerkategorien  trainingsSamples:  rr next.
     rr close.
     rr := nil

writeTrainingsSamples
     "write the class var TrainingsSamples to a file using ReferenceStreams"

     | rr |
     rr := ReferenceStream fileNamed: 'trainingssamples.obj'.
     rr nextPut: TrainingsSamplesFehlerkategorien  trainingsSamples .
     rr close.
     rr := nil


Nowadays I use JSON for this.


Cheers,


Herbert
