 Stores the input value into a variable.
-Think of a variable as a container with a nametag that can only store one value at a time.
-If you were to set another value to a variable, it will overwrite the previous value of that variable.
-You can get/output the value from a variable with the same name, type and mode using the [[Get Variable]] block.
+See [[Variables]] for more information.

+== Notes ==
-== Global variables ==
+If {{Port|?|Value}} remains not wired, the variable will not be overwritten.
+This could be used to provide default values for a custom script block:
-Let's say you have a script inside a block that sets a variable to 1, and you have a script outside of the block to inspect that variable.
+[[File:Set_Variable_default_value.png|thumb|none|Demonstration applying a default value, 2. The variable is global for inspection.]]
-{{Image|Set_Variable_global_example.png|Set Variable on a script block. On the ground, inspecting its value shows 0 due to locality.}}
+== Related ==
-As you can see, we've set the variable to 1, but the Get Variable block outputs 0 as if we never set the variable in the first place.
+* [[Variables]]
+* [[Get Variable]]
-This is because those two variables are local, meaning they can't transfer variable information from one place to another (inside a block to outside the block, or into another block and vice versa).
+* [[List Element]]
+* [[Set Reference]]
-If we want a variable to share information to another variable in different places, then we would have to globalize them.
-You can simply press the Global button on the keyboard where you type the variable's name. Global variables gain a <code>$</code> at the start of their name.
-Note that two variables with the same name with one being a global will not count as the same variables (e.g <code>Number</code> and <code>$Number</code> are not the same).
-{{Image|Set_Variable_button_global.png|Keypad shown with mode being changed to Global.}}
-== Saved variables ==
-Saved variables were added in Fancade 1.6. Like global variables, you can make a saved variable by pressing the Local/Global/Saved button on the keyboard where you type the variable's name.
-Saved variables gain a <code>!</code> at the start of their name.
-{{Image|Set_Variable_button_saved.png|Keypad shown with mode being changed to Saved.}}
-As the name implies, saved variables persist their value from one game session to the next.
-This is true whether the user ends the game by winning, dying, or simply pausing and returning to the menu.
-Additionally, saved variables are shared across all levels in the same game.
-This allows a player's actions in one level to affect their gameplay in other levels, and to keep track of purchases from the [[Menu Item]] block.
-Saved variables currently only have number type and there can be up to 64 saved variables per game.
