Parameters are a means of passing information between two or more procedures and between the WhereScape RED environment and procedures. Parameters can be added or removed from a Project.
Following is an example of the menu displayed when you right-click a parameter object.

WhereScape RED supports keyboard shortcuts—the underlined letter of a menu option. For example, pressing P opens the Properties window of the selected table, pressing C creates the index, etc. Ensure that the Windows > Control Panel > Ease of Access setting associated with keyboard shortcuts is enabled, to display keyboard shortcuts in RED. Refer to the relevant MS Windows documentation for details.
