Flags 0, 1, 2, 3, and 4 have no preassigned meanings. That is, their states will mean whatever you define them to mean in a given program. (See the example below.) Flag 5, when set, will interrupt a program when an overflow occurs within the program, displaying #$ and ¤. An overflow occurs when a result exceeds the largest number that the calculator can handle. The largest possible number is substituted for the overflow result. If flag 5 is clear, a program with an overflow is not interrupted, though #$ is displayed briefly when the program eventually stops. Flag 6 is automatically set by the calculator any time an overflow occurs (although you can also set flag 6 yourself). It has no effect, but can be tested. Flags 5 and 6 allow you to control overflow conditions that occur during a program. Setting flag 5 stops a program at the line just after the line that caused the overflow. By testing flag 6 in a program, you can alter the program's flow or change a result anytime an overflow occurs. Flags 7, 8 and 9 control the display of fractions. Flag 7 can also be controlled from the keyboard. When Fraction-display mode is toggled on or off by pressing { , flag 7 is set or cleared as well. Flag Status Fraction-Control Flags 7 8 9 Clear (Default) Set Fraction display off; display real numbers in the current display format. Fraction display on; display real numbers as fractions. Fraction denominators not greater than the /c value. Reduce fractions to smallest form. Fraction denominators are factors of the /c Value. No reduction of fractions. (Used only if flag 8 is set.)
