BREAK():{Error,return-value} ---------------------------- This is a Read-Eval-Print loop, similar to the top level loop, except that the following IDs at the top level cause functions to be called rather than being evaluated: ? Print this message, listing active Break IDs T Print stack backtrace Q Exit break loop back to ErrorSet A Abort to top level, i.e. restart PSL C Return last value to the ContinuableError call R Reevaluate ErrorForm!* and return M Display ErrorForm!* as the "message" E Invoke a simple structure editor on ErrorForm!* (For more information do Help Editor.) I Show a trace of any interpreted functions See the manual for details on the Backtrace, and how ErrorForm!* is set. The Break Loop attempts to use the same TopLoopRead!* etc, as the calling top loop, just expanding the PromptString!*.
