View source for Run Length Encoding

Run Length Encoding is a very simple form of file compression. It compresses long sequences of the same byte to an indicator code, byte value, and count. For example, 48 spaces (character code &20) might be encoded as &E9 &30 &20, assuming the indicator code was &E9.

CPC programs to use RLE techniques included:

* [[SQ23]]
* [[Crunch]] by [[Crown]]
* [[Newsweep]] ([[CP/M]])
* [[PowerPage]] (for saved pages)
* [[Stop Press]] (for clip art)
* [[MicroDesign]] (for all saved graphics)

Later compression programs (such as [[Cheese]] and [[Columbia]]) used the more advanced [[LZW]] algorithm.
