Variables

Introduction #

Variables are containers for storing data values (including numbers and strings), that can be reused over and over again.
Variable names are case sensitive, meaning that “Variable” and “variable” are not going to have the same value.

Variables can be used as parameters or inside any string. If the input box name contains a , you can type the variable name as it is. If the input box does not contain a , you need to wrap any variable in /$ $/, i.e. /$MyVariable$/.

Value of a variable can be:

Another variable - myVariable or /$myVariable$/
Real value (number) - 50
String - "My Cat"
Stack value [index]stackname - [2]myStack
Math expression including variables and Complex Math operators. Must be wrapped in (). - (myVariable * 10 - [2]myStack + 3)

All variables inside Receiver are global and get deleted every time you close or reset Receiver.
Variables are not unique to a button that created them and any button/deck can access them.

Press Tab in the main screen of the Receiver to view all the existing variables.

Math: Change Variable #

Creates a new variable or modifies an existing one.

Variable names can contain numbers, letters and _, but cannot start with a number itself.

Box Name	Type	Description
Variable	String	Name of the variable.
Operator	Dropdown	Operator you wish to use on the value.
Value	Any	Whatever you want to set the variable value to. Can contain complex math.

Examples of usage #

The table containing examples below assumes we have the following variables and stack:

Green marks a good example and red marks a bad example.
Bad examples can result in LB crashing. Click on the for explanation.
var = variable, str = string

Edit

Math: Clear Variable #

Clears a single variable. It removes it from the list of variables as well (accessible from the main menu by pressing TAB).
Useful command to keep your variable list clean and organized.

Pressing reset button automatically clears all variables.

Box Name	Type	Description
Variable	String	Name of the variable to clear.

Edit

Math: Get Variable Type #

Returns a string indicating the type of the variable:

"number" for numbers
"string" for variables containing text
"undefined" for variables that aren’t defined (do not exist)

Pressing reset button automatically clears all variables.

Box Name	Type	Description
Variable Name	String	The variable to get the type of.
Variable Save	String	Variable to save the result in.
