Versions using Control Characters
The general principle as previously described always starts with a counter, which defines both the type and the number of following symbols. Alternatively a control character can be used indicating a run embedded in unchanged data. Thus the capacity required for the counters can be reduced, but on the other hand the code length for a run increases accordingly.
