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
z
, flag 7 is set or cleared as well.

Flag 10 controls program execution of equations:
When flag 10 is clear (the default state), equations in running programs
are evaluated and the result put on the stack.
When flag 10 is set, equations in running programs are displayed as
messages, causing them to behave like a VIEW statement:
1. Program execution halts.
2. The program pointer moves to the next program line.
3. The equation is displayed without affecting the stack. You can clear
the display by pressing
a
or

that key's function.
