Cyclic Table Probes by Dr. James Powell is a package for creating custom probes with “history"; showing the last N values rather than just the latest. Values are displayed in a “cyclic” table, which wraps around automatically when it reaches the bottom of the display window (resizable).

The software was developed to support messaging systems, where messages can be handled too quickly for the eye to see with a last-value probe. Included are some standard probes, for strings, variants, objects, and some numeric types. Also included is a "Text Variant" probe, for messaging using a cluster of such, and a "JKI State Queue" probe for use in designs using the JKI "state machine". But the expected use case is for very easily creating custom probes for whatever messages or datatypes one is using (just modify one of the included probes).

Also contains “Quick Timer” probes. Use in pairs to measure execution times of portions of code.
