Lesson 21. Running DOS Applications > Long Filenames and DOS Applications - Pg. 113

Running DOS Applications 113 Configuring a DOS Application When a DOS program is started, a special area in memory is carved out, and a certain amount of system resources is allocated to the program. Some programs might need to make some adjust- ments to the resource allotment in order to run properly under Windows. Each DOS program has its own properties, just like any Windows program. To change these prop- erties, you use the Properties dialog box: 1. 2. 3. Click the Properties button on the toolbar. Click the appropriate tab and select the options you want. For example, to change the pro- gram's memory requirements, click the Memory tab. Click OK. Long Filenames and DOS Applications DOS applications don't understand the longer filenames commonly used under Windows. So when saving your files, you'll need to restrict yourself to using only eight characters, plus a three-character extension, like this: CARSALES.WKS. You don't have to worry about forgetting this requirement; the program won't let you use more characters in your filenames. But if you need to export a file from some other program and then use it in your DOS program, you'll need to remember the eight plus three restriction. Copying, Cutting, and Pasting Text
