Program execution is also automatically halted when the calculator overflows (refer to page 90) or attempts an improper operation that results in an Error display. Either of these conditions signifies that the program itself probably contains an error. To determine at which program line execution has halted (in order to locate the error), press any key to clear the Error display, then press fs to set the calculator to Program mode and display that program line. You may also want to display the current program line (by pressing fs) if your program has halted at one of several t instructions in your program and you want to determine which one that is. To continue executing the program afterward: 1. Press fs to set the calculator back to Run mode. 2. If you want to resume execution from the program line at which execution halted rather than from line 000, press gi followed by three digit keys that specify the program line desired. 3. Press t to resume execution. Stopping Program Execution Manually. Pressing any key while a program is running halts program execution. You may want to do this if the calculated results displayed by a running program appear to be incorrect (indicating that the program itself is incorrect). To halt program execution during a pause in a running program (that is, when gu is executed), press any key. After stopping program execution manually, you can determine at which program line execution has halted and/or resume program execution as described above.
