8.2.16 Modifying Variables in Programs
You can also use ISY Programs to modify variables. You can perform standard arithmetic
functions on a variable, change a variable to a specific value, or modify a variable’s Init
state.
The following functions can be performed on a variable:
Command Function Performed
= Sets the variable to a specified value.
+= Adds to the variable
-= Subtracts from the variable
*= Multiples the variable
/= Divides the variable
%= Performs a remainder function on the variable
&= Performs an AND (binary) function on the
variable
|= Performs an OR (binary) function on the
variable
=Random Sets the variable to a number between 1 and
the specified number
Init To Sets the variable’s initial value
For example, the following screenshot increases a variable by 1:

This example sets the Init value of a variable to the current value of another variable:
(This applies to firmware v5 and above)
