Program execution is also automatically halted when the calculator overflows (refer
to page 73) 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 00, press gi followed by two 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
u 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.
