HINT: To run the same program again, click the arrow to the right of the text box and select the command line from the drop-down list. Saving your work Before you turn off the computer, save your work on the hard disk drive or diskette/CD. This is one of the most important rules of computing. TECHNICAL NOTE: Save your data even when you are using the Standby command, in case the main battery discharges before you return to work. Saving documents is quick and easy, so it is a good idea to get in the habit of saving frequently. Many programs offer a feature that saves documents at regular intervals. Check your program’s documentation to see if it has an automatic save feature. 92 92 Learning the Basics Saving your work Saving files 1 On the File menu of your Windows® program, click Save. If you are working with a document that already has a file name, this is all you need to do. If you created a new document, your program displays a Save As dialog box. Use this dialog box to specify where to store the document and to give it a file name. Sample Save As dialog box 2 Choose the drive and folder where you want your file to be stored. 3 Type a file name, then click Save. HINT: To make another copy of the file you are currently working with, choose Save As from the File menu and give the new file a different name. File names The Windows® operating system supports file names of up to 255 characters long and include spaces. Some applications still require file names limited to eight characters. Learning the Basics 93 Printing your work You may use all the letters and numbers on the keyboard plus these characters: _ ^ $ ~ ! # % & { } ( ) @ and ‘. File names are not case-sensitive. Using a file extension Most programs assign an extension to the file name that identifies the file as being created in the program with a particular format. For example, Microsoft Word saves files with a .doc extension. Any file name with an extension of “.doc” is assumed to be a Microsoft Word file. Creating your own extension is usually unwise, since the program is unlikely to recognize a strange extension and may refuse to handle your file correctly. TECHNICAL NOTE: By default, the Windows® operating system does not show file extensions. For information on showing or hiding file extensions, see your Windows® operating system online Help. Printing your work Ensure the operating system is set up for your printer as described in “Setting up a printer” on page 70. HINT: You only need to set up the printer the first time you connect it. If you use more than one printer or are changing printers, you will need to set up the Windows® operating system to run with the additional printer(s). To print a file: 1 If your printer is not on, turn it on now. 2 Open the File menu of your Windows® program and click Print. 94 94 Learning the Basics Backing up your work The program displays a Print dialog box.
