<<button>>
The «button» macro creates a button, a special type of link that, when clicked, sets the data entered into other form macros in the passage (<<textinput>>, <<radio>>, <<checkbox>>), and moves to another passage.
Usage
The «button» macro should be provided with the familiar link syntax:
<<button [[displayed text|passage name]]>>
The resulting button behaves identically to a normal link, but, when clicked, additionally causes the data entered into <<textinput>>, <<radio>> and <<checkbox>> macros to be placed in the variables.
For instance, if the macro «textinput $FoodName» appears in the same passage with a «button», and the text “pretzels” has been entered into the input box, then clicking the button will, in addition to changing passages, run the equivalent of «set $FoodName to “pretzels”».
