Simple switch toggle function, if the value passed is 1 the result is 0 and vice-versa. Doesn't use an if statement so should be faster. The only possible input and output values are 0 or 1.

This is my Custom Function and I want to edit it


How does this work, Is "State" a new FileMaker command I am not aware of yet?

Another pretty common way would be to use "not", ie:

not State

... kudos for working xor into a Filemaker Calc!!!


To answer Bob: State is just the author's parameter naming. It could also have been written like:

Toggle ( boolean ) = where "boolean" is a boolean number, 0/1.

Jonathan - I like your way even better. I guess 'xor 1' and 'not' are the same thing if effect.

Sorry if me calling the parameter 'state' is confusing. Maybe I should change it to 'switch' instead?

Interesting method
I use Abs ( state - 1 )
to do the same thing...

Presumably no real efficiency differences.
