Depending on the configuration option where it is used, VBScript is available for configuration expressions to either calculate a value (file name, folder, property value, and so on) or to evaluate to True or False to apply an option (input required, field visibility, field read-only, and so on). You can use VBScript expressions in many places in a vault's configuration, including:
-
Property pages
-
Document naming
-
Folder naming
-
Lookup list tables and database queries
-
Custom commands
-
Workflow definitions
-
Reports
-
Document types
-
Database Import Wizard
Each configuration expression is a single VBScript statement to be evaluated. Configuration expressions are limited in that they:
-
Cannot contain more than one line of code, although they can call a predefined function that contains multiple lines of code.
-
Cannot use variables.
-
Should not execute other actions outside the scope of the current document, change property values, invoke long-running functions, or invoke any user interface functions. Such actions can have unexpected or unpredictable results.
You can use a VBScript expression anywhere you see the Meridian Enterprise Script Editor button 
in Configurator. Clicking the button opens the Meridian Enterprise Script Editor where you can enter a VBScript expression. For information about using the Meridian Enterprise Script Editor, see Understanding the Meridian Enterprise Script Editor.
