Creating a Text File (Apex/ClearCase) This module guides you through the steps needed to create a simple text file. All Apex components (code, documentation, etc.) .

Average Time to Complete this Module
Creating SubsystemsApex supports the dividing of a software-development effort into high-level components called subsystems, each containing a group of logically related objects. Subsystems let you group related files, Ada packages and other compilation units together, hiding those that contain only implementation details.
Note: In UNIX, a Rational subsystem is a directory with a .rss filename extension.
Models
One important characteristic of a Rational subsystem is its model. A model is a Rational subsystem that serves as a prototype for another Rational subsystem. The model provides a base structure of subdirectories, policies (compiler options, target keys, etc., by way of switches), and a base set of Imports.
Creating a SubsystemIn this exercise, you will create a subsystem named test.rss.
- 1. . Open a directory-viewer window of your VOB (/vob/test) if one is not opened.
- 2. . Choose the New command from the File menu. Apex displays a cascading menu.
- 3. . Choose the New Subsystem menu item from the New submenu. Apex displays the New Subsystem dialog box:
![]()
- 4. . Enter the full pathname of the subsystem you wish to create in the Subsystem Full Name field. The .rss extension is added for you automatically. For this exercise, use $/vobs/test/test.
- 5. . Because we will be creating a text file, the Language is not important, so use the default of Ada. Verify the Host Architecture matches the architecture of the machine on which you are running.
- 6. . Make sure the Visit the new subsystem check box is selected.
- 7. . Select the Make it an element option so that this Rational subsystem will be controlled. Any element that is controlled needs the enclosing Rational subsystem to be controlled. If you do not control it now, it will need to be controlled when you control the first element in this Rational subsystem. When you select this option, a Note field will be displayed. Enter a Note to be associated with controlling this element.
To create your new Rational subsystem, click OK or Apply. When the dialog box closes with the Visit the new subsystem check box selected, Apex opens a directory-viewer window showing you the subsystem that was created.
See File > New for more information. The Online Reference contains additional information on the contents of an empty subsystem.
Creating a Text FilePerform the following steps from the directory viewer displaying the subsystem (test.rss should be the first line in the directory viewer) you created in the previous topic. If you do not have it displayed, execute the File > Open command and enter <dir>/test.rss, where <dir> is the path to your subsystem as the Filename.
- 1. . Select the New command from the File menu in the test.rss directory-viewer window. Apex opens a cascading menu.
- 2. . Choose the New File menu item from the New submenu. Apex displays the New File dialog box.
- 3. . Enter the name text.txt in the Name field.
- 4. . Execute the New File dialog box by clicking the OK button.
When you complete step four, Apex creates an empty file in an editor window.
Editing the Text FileThe Editor Window
The editor window is where you edit your text files. All the Apex editors operate in the same basic manner. Type in anything you wish in your text file.
Basic tips for using the editor:
- To type new text, move the blinking cursor to the exact insertion point where you want to enter text. You can use the arrow keys to move the cursor, or you can click the mouse pointer on the space you want the cursor to appear.
- The editor window is always in insert mode; unlike other line editors (vi, for example) you can type and move the cursor without toggling the command mode.
- To delete the previous character, use the Delete or Back Space keys.
There are many editor key bindings.
Type anything in. Select the File > Save command to save your file.
