12/16/2023 0 Comments Does not equal sign alt code![]() PC keyboards designed for non-English use included other methods of inserting these characters, such as national keyboard layouts, the AltGr key or dead keys, but the Alt key was the only method of inserting some characters and the only method that was the same on all machines, so it remained very popular. (There were, however, many more code pages for a more complete list, see code page). A common choice in locales using variants of the Latin alphabet was CP850, which provided more Latin character variants. This causes the Alt combinations to produce different characters (as well as changing the display of any previously-entered text in the same manner). Some Eastern European, Arabic and Asian computers used other hardware code pages, and MS-DOS was able to switch between them at runtime with commands like KEYB, CHCP or MODE. In most cases typing a number greater than 255 produced the character associated with the remainder after the number is divided by 256. Some would interpret the code as a command, but often it would be interpreted as a code to be placed on the screen at the location of the cursor, thus displaying the corresponding 8-bit character from the current code page. Applications reading keystrokes from the BIOS would behave according to what action they associate with that code. It would place the corresponding code into the keyboard buffer so that it would look (almost) as if the code had been entered by a single keystroke. On IBM PC compatible personal computers from the 1980s, the BIOS allowed the user to hold down the Alt key and type a decimal number on the keypad. ![]() This is done by pressing and holding the Alt key, then typing a number on the keyboard's numeric keypad that identifies the character and then releasing Alt. On personal computers with numeric keypads that use Microsoft operating systems, such as Windows, many characters that do not have a dedicated key combination on the keyboard may nevertheless be entered using the Alt code (the Alt numpad input method).
