The PlanetPress Talk Editor has a solid set of features for debugging PlanetPress Talk scripts, including execution control, breakpoints, spies, expression evaluation, and changing the value of a variable during execution. Consult the PlanetPress Talk Editor section of the PlanetPress User Guide for a description of these features, and suggestions on other debugging techniques.
PlanetPress Talk includes a breakpoint command that you can enter anywhere you can enter a PlanetPress Talk script. See Breakpoint (procedure).
PlanetPress reports errors in PlanetPress Talk code in two places: the status bar of a dialog box when you are entering a PlanetPress Talk expression in a text box within that dialog box, and the Messages area of the PlanetPress Program Window (consult the PlanetPress User Guide for a description of the Messages area). You can also use these error reports to determine and fix problems in your code.
