An internal DOS/Windows command for creating a quick batch file or other text file. For example, to create the MAKECOPIES.CMD file, type the following and press Enter:copy con makecopies.cmdType the text and press Enter to end each line. Copy Con works a line at a time. You can backspace to delete characters on the same line, but you cannot go back and change previous lines. You will have to use Edit, Notepad or some other text editor to make changes. When done, press F6 (a ^Z appears) and Enter. The Mac/Unix/Linux equivalent is the Cat command (see cat).
