| |
| '''Code page 437''' is the [[Character encoding|character set]] of the original [[IBM PC]] (personal computer), or [[MS-DOS]]. It is also known as CP437, OEM 437,<ref name=GGDC/> PC-8,<ref name=PCMAG/> or MS-DOS Latin US.<ref name=DIS/> The set includes [[ASCII]] codes 32–126, extended codes for accented letters ([[diacritics]]), some Greek letters, icons, and line-drawing symbols. It is sometimes referred to as the "OEM font" or "high ASCII", or as "[[extended ASCII]]"<ref name=PCMAG/> (one of many mutually incompatible ASCII extensions).

|
| In a strict sense, this character set was not conceived as a [[code page]]; it was simply the graphical [[glyph]] repertoire available in the original IBM PC. This character set remains the primary font in the core of any [[Enhanced Graphics Adapter|EGA]] and [[Video Graphics Array|VGA]]-compatible graphics card. Text shown when a PC reboots, before any other font can be loaded from a storage medium, typically is rendered with this "Code Page".<ref>Systems available in Eastern European, Arabic, and Asian countries often use a different set. The designation "OEM", for "original equipment manufacturer", indicates that the "native" hardware character set supplied in ROM could be changed by the manufacturer to meet different markets.</ref> Many file formats developed at the time of the IBM PC, such as [[.nfo]], define this as the default encoding.

| The original IBM PC contained this font as a 9×14 pixels-per-character font stored in the [[Read-only memory|ROM]] of the [[IBM Monochrome Display Adapter|IBM Monochrome Display Adapter (MDA)]] and an 8×8 pixels-per-character font of the [[Color Graphics Adapter]] ([[Color Graphics Adapter|CGA]]) cards. The [[Enhanced Graphics Adapter|IBM Enhanced Graphics Adapter (EGA)]] contained an 8×14 pixels-per-character version, and the [[Video Graphics Array|VGA]] contained a 9×16 version.

| All these display adapters have text modes in which each character cell contains an [[octet (computing)|8-bit]] character [[code point]] (see [[VGA compatible text mode|details]]), giving 256 possible values for graphic characters. All 256 codes were assigned a graphical character in ROM, including the codes from 0 to 31 that were reserved in ASCII for non-graphical control characters.

| # as an ''information interchange code'' (through files and telecom), in which the values 0 to 127 play the same role as in ASCII and the codes 128 to 175 represent international text characters (see the table below);
| | |
| # as a ''graphical resource for screen and printers'' (whereby a character can be displayed or printed by sending the corresponding 8-bit code point), for which the full 256-code range can be used as graphical characters.

| == Alt Codes ==
| | </ul> |
| A legacy of code page 437 is the set of number combinations used in [[Windows Alt keycodes]] introduced in the first versions of [[MS-DOS]]. The user could enter a character by holding down the [[Alt key]] and entering the three-digit decimal Alt keycode on the [[numpad]]. The designers intended that these numbers would change as the current character set was changed. But when Microsoft switched to more standard character sets (such as [[CP1252]] and later [[Unicode]]) in Windows, so many users had memorized the numbers used by CP 437 that Microsoft had to retain the original codes (they added the ability to type a code in the current character set by typing the numpad 0 before the digits).
| |
| | |
| == Characters ==
| |
| The following tables show code page 437. Each character is shown with its equivalent [[Unicode]] code point and its decimal code point. See also the notes below as there are multiple equivalent Unicode characters for some code points.
| |
| | |
| === Interpretation of code points 1–31 and 127 === | |
| Code points 1–31 and 127 (00–1F<sub>hex</sub> and 7F<sub>hex</sub>) may be interpreted as either control or graphic characters, depending on the context. When used in a memory-mapped video display buffer, the code point is displayed as the graphic shown in the table of special graphic characters below. For printers the graphics context is established by a preceding control sequence in the data stream. In other situations, these code points are used as controls, as shown in the standard code page table.<ref name=IBM/>

| | |
| Most fonts for [[Microsoft Windows]] include the special graphic characters at the Unicode indexes shown, as they are part of the [[WGL4]] set that Microsoft encourages font designers to support. (The monospaced raster font family [[Terminal (typeface)|Terminal]] was an early font that replicated all code page 437 characters, at least at some resolutions.) To draw these characters directly from these code points, a [[Microsoft Windows]] font called MS Linedraw<ref>{{cite web|title=MS LineDraw - Version 2.00|url=http://www.microsoft.com/typography/fonts/font.aspx?FMID=708|work=Microsoft|publisher=Microsoft Corporation|accessdate=1 July 2012|author=Staff|year=2012}}</ref> replicates all of the code page 437 characters, thus providing one way to display DOS text on a contemporary Windows machine as it was shown in DOS, with limitations.<ref>{{cite web|title=WD97: MS LineDraw Font Not Usable in Word|url=http://support.microsoft.com/kb/179422 WD97|work=Microsoft|publisher=Microsoft|accessdate=1 July 2012|author=Staff|date=22 January 2007}}</ref>

| | |
| Along with the characters in the range 0 to 31 (00<sub>hex</sub> to 1F<sub>hex</sub>), which can be interpreted as ASCII controls as well as graphical [[dingbat]]s, some characters have overloaded meanings. Implementers of translation to Unicode should note that these codes do not have a unique, single Unicode equivalent and the correct choice depends upon context:
| |
| | |
| * 0 and 255 (FF<sub>hex</sub>) both draw a blank space, as does 32 (20<sub>hex</sub>). The use of 255 for U+00A0 Non-breaking space (NBSP) has some precedent in [[word processors]] designed for the IBM PC.
| |
| * 225 (E1<sub>hex</sub>) is both the German [[ß|sharp S]] (U+00DF, ß) and the Greek lowercase [[beta (letter)|beta]] (U+03B2, β).
| |
| * 227 (E3<sub>hex</sub>) is the Greek lowercase [[pi (letter)|pi]] (U+03C0, π), but early fonts such as [[Terminal (typeface)|Terminal]] use a variant of pi that is ambiguous in case, and therefore can be used for the Greek capital pi (U+03A0, Π) or the n-ary product sign (U+220F, ∏).
| |
| * 228 (E4<sub>hex</sub>) is both the n-ary summation sign (U+2211, ∑) and the Greek uppercase [[sigma]] (U+03A3, Σ).
| |
| * 230 (E6<sub>hex</sub>) is both the [[micro sign]] (U+00B5, µ) and the Greek lowercase [[mu (letter)|mu]] (U+03BC, μ).
| |
| * 234 (EA<sub>hex</sub>) is both the [[Ohm (unit)|ohm]] sign (U+2126, Ω) and the Greek uppercase [[omega]] (U+03A9, Ω). (Unicode considers the ohm sign to be equivalent to uppercase omega, and suggests that the latter be used in both contexts.<ref>The Unicode Consortium, ''The Unicode Standard 4.0'', Chapter 7, "European Alphabetic Scripts", p176. [http://www.unicode.org/versions/Unicode4.0.0/ch07.pdf#search=%22character%20U%2B2126%20maps%20OR%20map%20OR%20mapping%22 PDF version]</ref>).
| |
| * 235 (EB<sub>hex</sub>) is the Greek lowercase [[delta (letter)|delta]] (U+03B4, δ), but it has also been used as a surrogate for the Icelandic lowercase [[eth]] (U+00F0, ð) and the [[partial derivative]] sign (U+2202, ∂).
| |
| * 237 (ED<sub>hex</sub>) is supposed to be used as Greek lowercase [[Phi (letter)|phi]], but is mainly used as the [[empty set]] sign (U+2205, <math>\varnothing</math>) and was also used as the Greek phi symbol in italics (U+03D5, <math>\phi\,\!</math>) to name angles, diameter sign (U+2300, <math>\varnothing</math>), and as a surrogate for the Latin lowercase O with stroke (U+00F8, ø).
| |
| * 238 (EE<sub>hex</sub>) is both the Greek lowercase [[epsilon]] (U+03B5, ε) and the [[element (mathematics)|element-of]] sign (U+2208, ∈). Later it was often used for the [[euro sign]] (U+20AC, €).
| |
| | |
| == Difference from ASCII ==
| |
| Code page 437 is based on [[ASCII]], with the following modifications:
| |
| * Codes from the C0 control range (00<sub>hex</sub> to 1F<sub>hex</sub>) and ASCII DEL (7F<sub>hex</sub>) can assume their original function as control characters, but also function as graphic symbols when displayed in [[text mode]] from the [[screen buffer]]. For example, DEL and most of the C0 control codes are displayed graphically in a screen editor like [[MS-DOS Editor]] or when written to the screen via the DOS ''[[type (command)|type]]'' command; by writing directly to the screen memory rather than using the DOS or BIOS character-output functions, an MS-DOS application can display all of them on the screen. The graphics include smiling faces, [[card suit]]s, and musical notes. Code 127 (7F<sub>hex</sub>), DEL, shows as a "house". This behavior is not specific to code page 437, but shared by all DOS code pages and so-called [[Windows code page#Overview|Windows OEM]] code pages, which generally resemble code page 437.
| |
| * The high-bit range, 128 to 255 (80<sub>hex</sub> to FF<sub>hex</sub>), is mapped to various symbols: a few European characters (accented Latin letters, etc.) in no particular order and not sufficient for representation of some Western European languages; [[box-drawing characters]]; mathematical symbols; and a few [[Greek alphabet|Greek]] letters commonly used in mathematics and physics.
| |
| | |
| The repertoire of code page 437 was taken from the character set of [[Wang Laboratories|Wang]] word-processing machines, according to [[Bill Gates]] in an interview with Gates and [[Paul Allen]] that appeared in the 2 October 1995 edition of ''Fortune Magazine:''
| |
| | |
| : "... We were also fascinated by dedicated word processors from Wang, because we believed that general-purpose machines could do that just as well. That's why, when it came time to design the keyboard for the IBM PC, we put the funny Wang character set into the machine—you know, smiley faces and boxes and triangles and stuff. We were thinking we'd like to do a clone of Wang word-processing software someday."
| |
| | |
| The selection of graphic characters has some internal logic:
| |
| * Table rows 0 and 1, codes 0 to 31 (00<sub>hex</sub> to 1F<sub>hex</sub>), are assorted [[dingbat]]s (complementary and decorative characters). The isolated character 127 (7F<sub>hex</sub>) also belongs to this group.
| |
| * Table rows 2 to 7 (except character 127, 7F<sub>hex</sub>), codes 32 to 126 (20<sub>hex</sub> to 7E<sub>hex</sub>), are the standard [[ASCII]] printable characters.
| |
| * Table rows 8 to 10 (8<sub>hex</sub> to A<sub>hex</sub>), codes 128 to 175 (80<sub>hex</sub> to AF<sub>hex</sub>), are a selection of international text characters.

| * Table rows 11 to 13 (B<sub>hex</sub> to D<sub>hex</sub>), codes 176 to 223 (B0<sub>hex</sub> to DF<sub>hex</sub>), are [[Box drawing characters|box drawing]] and [[Unicode symbols|block]] characters. This block is arranged so that characters 192 to 223 (C0<sub>hex</sub> to DF<sub>hex</sub>) of the rows 12 and 13 (C<sub>hex</sub> and D<sub>hex</sub>) have all right arms (except 217 (D9<sub>hex</sub>)) or right filled areas (except 221 (DD<sub>hex</sub>)), and this is due to the following technical reason:<ref>Richard Wilton, Programmer's Guide to PC & PS/2 Video Systems, 1987, Microsoft Press.</ref> the original [[IBM PC]] [[IBM Monochrome Display Adapter|MDA]] display adapter stored the code page 437 character [[glyph]]s as [[bitmap]]s eight [[pixel]]s wide, but for visual enhancement displayed them every nine pixels on screen (eight plus an additional gap). Thus characters with connections at their right edge had to duplicate their eighth pixels to avoid visual interruptions in the designs built up with them. This ''pixel extension'' is done by special hardware circuitry, and only this character subset is affected.
| |
| * Table rows 14 and 15 (E<sub>hex</sub> and F<sub>hex</sub>), codes 224 to 255 (E0<sub>hex</sub> to FF<sub>hex</sub>) are devoted to mathematical symbols, where the first twelve are a selection of Greek letters commonly used in physics. Characters 244 (F4<sub>hex</sub>) and 245 (F5<sub>hex</sub>) are the upper and lower portion of an italic [[long S]], the symbol used as the [[integral sign]] ({{Unicode|∫}}), and they can be extended with the character 179 (B3<sub>hex</sub>), the vertical line of the box drawing block. Characters 249 (F9<sub>hex</sub>) and 250 (FA<sub>hex</sub>) are almost indistinguishable: the first is slightly larger than the second, which resembles the typographic [[Interpunct|middle dot]] (·). The character 255 (FF<sub>hex</sub>) is merely blank, and acts as a kind of [[non-breaking space]] in order to arrange math formulae.

| == Internationalization ==
| |
| Code page 437 has a series of international characters, mainly values 128 to 175 (80<sub>hex</sub> to AF<sub>hex</sub>). However, it lacks many characters important to several Western languages:
| |
| * [[Spanish language|Spanish]] (Á, Í, Ó, Ú), [[French language|French]] (À, Â, È, Ê, Ë, Ì, Î, Ï, Ô, Œ, œ, Ù, Û), and [[Portuguese language|Portuguese]] (Á, À, Â, Ã, ã, Ê, Í, Ó, Ô, Õ, õ, Ú).
| |
| * [[German language|German]] [[sharp S]] (ß) shares its code point with the [[beta (letter)|beta]] symbol (β), which is acceptable at the low resolution on the original IBM CGA hardware, but unacceptable at higher resolutions. Most newer glyph sets for code page 437, including those built into the IBM EGA and VGA graphics cards, prefer the German sharp S shape for this character.
| |
| * Scandinavian lacks slashed-o 'Ø' and 'ø'. Character number 237 (ED<sub>hex</sub>), the empty set symbol, could be used as a surrogate, but its spacing is awkward for display within a word. To compensate, the [[Danish language|Danish]]/[[Norwegian language|Norwegian]] and [[Icelandic language|Icelandic]] code pages ([[Code page 865|865]] and [[Code page 861|861]]), replaced cent mark (¢) with 'ø' and yen (¥) with 'Ø'.
| |
| * Most [[Greek alphabet]] symbols were omitted, beyond the basic math symbols. (They were included in the Greek-language code pages [[Code page 737|737]] and [[Code page 869|869]].)
| |
| | |
| Along with the [[cent (currency)|cent]] (¢), [[pound sterling]] (£) and [[yen]]/[[Chinese yuan|yuan]] (¥) currency symbols, it has a couple of former European currency symbols: the [[Dutch guilder|florin]] (ƒ, Netherlands) and the [[Spanish peseta|peseta]] (₧, Spain). The presence of the last is unusual, since the Spanish peseta was never an internationally relevant currency, and also never had a symbol of its own; it was simply abbreviated as "Pt", "Pta", "Pts", or "Ptas". Spanish models of the [[IBM Electric typewriter|IBM electric typewriter]], however, also had a single position devoted to it.
| |
| | |
| Later MS-DOS character sets, such as [[code page 850]] (DOS Latin-1), [[code page 852]] (DOS Central-European) and [[code page 737]] (DOS Greek), filled the gaps for international use with some compatibility with code page 437 by retaining the single and double box-drawing characters, while discarding the mixed ones (''e.g.'' horizontal double/vertical single). All code page 437 characters have similar glyphs in [[Unicode]] and in Microsoft's [[Windows glyph list 4|WGL4]] character set, and therefore are available in most fonts in [[Microsoft Windows]], and also in the default VGA font of the [[Linux]] kernel, and the [[Universal Character Set|ISO 10646]] fonts for [[X Window System|X11]].
