platform.registerErrorHandler is a function that is part of the platform.

This function sets the error handler callback function for the script. Setting an error handler callback function provides control over what happens when an error is encountered in the script. Returning a true value lets the script continue, ignoring the error (no error screen).

The error handler callback function will not be called for errors that occur during initialization or within on.restore.

This has been introduced in TI-Nspire OS 3.2 (Changes).


platform.registerErrorHandler(function(lineNumber, errorMessage, callStack, locals) ... end)
