DOCUMENT:Q32866 17-DEC-2000 [msdos] TITLE :Entering and Displaying Control Characters in TELNET or EDLIN PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:2.x3.x,4.x,5.x OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 2.11, 3.1, 3.2, 3.21, 4.0, 4.01, 5.0, 5.0a ------------------------------------------------------------------------------- SUMMARY ======= To enter a control character into a text file using EDLIN, press CTRL+V followed by the character that identifies the particular control character desired (if that character is an alphabetic character it must be capitalized). For example, to enter CTRL+G (ASCII character 07h) in EDLIN, type CTRL+V followed by the capital letter G. EDLIN will display this particular input as ^VG. Please note that EDLIN displays control characters differently, depending on whether you are entering text or you are listing some lines in a file. In the previous example, EDLIN represents CTRL+G as ^VG when you are inputting text. However, when you exit EDLIN's input mode and list the line that contains the CTRL+G character, EDLIN displays the CTRL+G as ^G. This behavior is consistent with all control characters except CTRL+I (tab), CTRL+J (linefeed), and CTRL+M (carriage return); when EDLIN lists a line that contains these characters, it interprets them literally. MORE INFORMATION ================ The following is a list of ASCII control-code characters, 0 through 31, that many try to include in a text file. The most common control-code character is the ESC-key character, ASCII value 27 decimal.
