Setting and clearing Flags
Method 1
Use this method only if the flag you want to change is listed in the System
Flags list.
1. With the System Flags list displayed, higlilight the flag that you want to
set or clear.
You can do this by either:
® pressing the ® or ® keys imtil the flag you want is highlighted or
• typing the first digit of the number of the flag.
See the previous section for instructions on displaying the flags.
2. Press CHK.
If the flag was set before, it is cleared; if it was clear before, it is now
set.
3. Press OK or (ENTE^ to return to the Calculator Modes screen and OK or
(ENTER) again to return to yom default screen.
Method 2
If you know the number of the system flag you want to change, you can
change the flag from the command line. The syntax you use depends on
the operating mode you have chosen: algebraic or RPN.
In algebraic mode, the syntax is:
commandijlag)
In RPN mode, enter the flag on the first level of the stack and then enter
the appropriate command. The command for setting a flag is SF and the
command for clearing a flag is CF. (The flag commands are described on
page 2-4.)
For example, to set flag -40 in algebraic mode, you enter SF(-40) and
press (ENTER). In RPN mode, you enter -40 onto level 1 of the stack, enter SF
onto the command line and press (ENTER).
Similarly, to clear flag ^0 in algebraic mode, you enter CF(-40) and press
(ENTER). In RPN mode, you enter -40 onto level 1 of the stack, enter CF onto
the command line and press (ENTER).
You can use this method to set and clear all flags, not just those listed on
the System Flags list.
