The ASCII (American Standard Code for Information Interchange)character set used by MS-DOS contains 256 characters. Many of thesecharacters are not located on the computer keyboard; however, you canenter these characters by using a different code page.
The ASCII character set consists of 256 codes or characters. The first128 codes represent the alphabet, numbers, punctuation, and controlcharacters. The other 128 codes are extended characters, and includeEuropean characters, graphics, and scientific characters. Theseextended characters are not represented on the keyboard.
To enter an ASCII character that is not represented on the keyboard,do the following:
At the command prompt, type:
(Where [drive] specifies the drive where MS-DOS is installed, and [path] specifies the directory where MS-DOS is installed.)
The active code page is returned. See the Microsoft MS-DOS User's Guide" for version 5.0, 6.0, or 6.2 to find the Code Page Table for the returned code page.
Locate the character in the code page table to be displayed. The character has a corresponding integer value that represents its decimal equivalent.
At the command prompt, hold down the ALT key while typing the character's decimal equivalent on the numeric keypad.
NOTE: You MUST use the number keys on the numeric keypad when typing an extended character key combination.
MS-DOS versions 5.0, 6.0, and 6.2 reserve characters 0 through 31 forcontrol characters. These characters, except numbers 20 and 21, willnot be displayed when entered from the command prompt. Characters 32through 127 are located on the keyboard, and characters 128 and aboveare extended characters.
If the above process does not enable the display of extended ASCIIcharacters in an MS-DOS based application, contact your hardwaremanufacturer to ensure that support for these characters is provided.
