Sample input:
Toggle ( 1 )
Sample output:
0
Function definition: (Copy & paste into FileMaker's Edit Custom Function window)
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.

| 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. |
