Arithmetic Comparisons

---

Arithmetic comparisons can be used anywhere that a bit expression is allowed. They are seen as TRUE if the comparison works, FALSE otherwise. There are six arithmetic comparisons that can be made. Like the Logical Operators, these also have both text and "C" representations. They are:

Function	Symbol
Less Than	LT
Less Than or Equal To	LE
Equal To	EQ
Greater Than	GT
Not Equal	NE

To indicate that it's a comparison, the notation is enclosed in square brackets. The result can be used anywhere a bit variable is referenced. A comparison might look like this:

[ JS1.A1 > JS2.A1 ]

which is TRUE if JS1.A1 is greater than JS2.A1.

It should be noted that the square brackets MUST enclose the comparison, even when the comparison is already enclosed in parentheses as might be the case in an IF/THEN sequence (discussed later).

Comparisons can be used for several things. For example, activating WEP when the throttle is above a certain position. Keeping in mind that axis values range from 0 to 255 and that maximum throttle is really the minimum value internally, and assuming the throttle is on JS1.A3, you could write:

SCRIPT
  CMS.B1 = [JS1.A3 < 25];
ENDSCRIPT

and cms.b1 will be on whenever JS1.A3 has a value greater than about 90%. The CMS.B1 button is then programmed in the GUI to send a character or activate a DX button to control WEP.
