I do something like this with the text output of my scripts, when debug mode is enabled: https://imgz.org/i6DpehGZ-1280.png

Each character corresponds to one line in the debug log, and is determined (via hashing) by the subprocedure writing to the log.

It gives me a "general feel" of what's going on, and makes it easy to, at minimum, detect infinite loops.
