# Local Variables

A Variable is a memory zone where you can store and retrieve information. For each Form, you have 100 Variables where to store information in. The content of a Local Variable is available only on the Form where it belongs. This means that Local Variable 0 in Form “frm\_Main” can have a different content than Local Variable 0 in Form “frm\_Products”. You can change the content of a Local Variable through Action “Set Var”. In Expressions, Local Variables are identified as LVAR().

For your own organization, you can name the Local Variables. Select the Local Variable that you want to rename on the Table and press the edit button to edit its properties.

* **Variable** - Local Variable Identifier. You cannot change this value.
* **Name** - Local Variable Name. Name that you want to give to the Local Variable. The name of the Local Variable should only contain letters, digits or underscore (\_). This is the Name that will identify the Local Variable throughout the Project.
* **Description** - Local Variable Description. Description that you want to give to the Local Variable. This property is for your information only.

Next to the table are three icons with the following function:

* **Modify Local Variable** - Modify the selected local variable.
* **Reset** - Reset the selected variable taking into account the following options:
  * *Reset* - Reset the selected local variable
  * *Reset Unused* - Reset only those local variables that are not being used
  * *Reset All* - Reset all created local variables
* **Check Usage** - This is a shortcut to the [Find ](/kalipso5/using/find.md)option. Indicates where the selected object is being used.

By right-clicking on a variable, a popup menu is accessed that replicates the last two options previously described.
