An attempt was made to alter a read-only file. Use one of the following procedures to edit a read-only file: ■ Use the Read Only command in the Edit menu to turn off the current window's read-only attribute. You can edit the file once it's off; however, the file's read-only attribute is still on. To retain your edits, use the Save As command in the File menu and save the file to a new name. ■ Use the DOS Shell command in the File menu to open a shell to DOS. Then use the MS-DOS ATTRIB command to turn the file's read-only attribute off. Type EXIT to return to QuickPascal from the shell.
