Boolean values: Difference between revisions

AppleScript has built-in boolean keywords <code>true</code> and <code>false</code>. Numbers do not work in place of boolean expressions, but they do coerce to and from.

<lang AppleScript>1 > 2 --> false

not false --> true

{true as integer, false as integer, 1 as boolean, 0 as boolean}

--> {1, 0, true, false}

true = 1 --> false</lang>

AppleScript also has constants <code>yes</code> and <code>no</code>, which coerce easily to boolean values, and are interchangeable with them in AppleScriptObjC.

<lang AppleScript>{yes as boolean, no as boolean}

--> {true, false}</lang>

However, <code>yes</code> and <code>no</code> do not coerce to integer values.
