Start Parameter Editing

To edit parameters

1. Pull down the Customize menu in the Main Window.
2. Click the pointer on the Parameters menu item.
3. Choose a menu item from that submenu.

   Only one user at a time is allowed to edit data in the parameter file PSDC$PARAMS.DAT. The file is locked by anyone using any editor. If the file is locked by another user when you initiate any of the parameter menu's submenus, a message box appears explaining that read-only access to the file is allowed. You are able to view the contents of the file, but any requests to change data are denied. Should the file become unlocked during the course of your DECwindows Motif session, a second message box appears asking you if you would now like update capabilities.

4. Indicate your choice by clicking either Yes or No.

   After you gain updated access to the file, it is unavailable to other users. Whenever you close one of the parameter editor's dialog boxes, you are asked if you would now like to release the file, as shown in the following example:

   

5. When you complete your set of changes to the file, click Yes in response to this request.

   Otherwise, as long as your DECwindows Motif session remains active, even though you may be doing other tasks, such as graphing, you still have the file locked.

   A reminder of the status of the parameter file appears in the main window.
