About variables

Forms use variables to communicate between themselves and to save environment information across form executions. Some variables are temporary. Persistent variables are loaded to and from disk. Variables can be global or associated with a particular form. Both temporary and persistent variables can be used by VB scripts. Components can be bound to variables.

For example, a global persistent variable can be used to store the ID of the last customer a user was interacting with, so that any forms that are subsequently launched can automatically navigate back to that customer.

Variable attribute	Description
Name	For global variables, an internal name unique in the forms database. For form-level variables, an internal name unique to the form.
Description	A description of the variable.
Value	The value of the variable. You can use WinStudio keywords and their parameters to specify values.
Persistent or Temporary	The values of persistent variables are loaded to and from disk, so they are saved when the form closes. The values of temporary variables exist only while a form is open.
Global or Form-level	Variables that are global objects can be used by more than one form. Once the global attribute is set, it cannot be altered. Form-level variables are unique to one form.
