| ARTICLES RELATED TO EBCDIC | | | | |  EBCDIC: Encyclopedia II - DVI file format - SpecificationThe DVI format was designed to be compact and easily machine-readable. Toward this end, a DVI file is a sequence of commands which form "a machine-like language", in Knuth's words. Each command begins with an eight-bit opcode, followed by zero or more bytes of parameters. For example, an opcode from the group 0x00 through 0x7F (decimal 127), set_char_i, typesets a single character and moves the implicit cursor right by that character's width. In contrast, opcode 0xF7 (decimal 247), pre (the ...

The most notable of these is the windows-1252 code page, which contains a range of typographical punctuation characters, the euro sign, and a few other special characters, in character positions which were reserved for control ...

| | | | | EBCDIC: Encyclopedia II - Character encoding - Modern encoding model Unicode and its parallel standard, ISO 10646 Universal Character Set, which together constitute the most modern character encoding, broke away from this idea, and instead separated the ideas of what characters are available, their numbering, how those numbers are encoded as a series of "code units" (limited size numbers), and finally how those units are encoded as a stream of octets (bytes). The idea behind this decomposition is to establish a universal set of characters that can be encoded in a variety of ways. To correctly describe this model needs more ...

| | | | | | | EBCDIC: Encyclopedia II - Binary-coded decimal - Basics To BCD-encode a decimal number using the common encoding, each digit is encoded using the four-bit binary bit pattern for each digit. For example, the number 127 would be:
0001 0010 0111
Since most computers store data in eight-bit bytes, there are two common ways of storing four-bit BCD digits in those bytes:
each digit is stored in one byte, and the other four bits are then set to all zeros, all ones (as in the EBCDIC code), or to 0011 (as in the ASCII code) ...

| | | | | EBCDIC: Encyclopedia II - E - Usage Like other Latin vowels, e came in a long and a short variety . In modern English, the long variety is sounded as in see and the short as in pet. However, Latin and most European languages sound the long variety differently, as in English vein. In other languages which use the letter it takes on various other values, sometimes with accents to indicate which one (ê é è ë ē ĕ ě ẽ ė ẹ ę). Digraphs starting with E are common in many languages to indicate diphthongs or show a different value of E, such as EA or E ...

| | | | | EBCDIC: Encyclopedia II - F - History F developed from the digraph FH that stood for /f/.
The Etruscans were the inventors of this digraph; F on its own stood for /w/ in Etruscan as in Greek (where the letter F, called Digamma in Greek, has disappeared due to the fact that the /w/ phoneme itself disappeared.) The origin of F is the Semitic letter wâw that also represented /w/ and originally probably represented a hook or a club.
The minuscule f is not to be confused with ſ, the archaic long s (or medial s). For example, "sinfuln ...

| | | | | EBCDIC: Encyclopedia II - String computer science - String datatypes A string datatype is a datatype modeled on the idea of a formal string. Strings are such an important and useful datatype that they are implemented in nearly every programming language. In some languages they are available as primitive types and in others as composite types. The syntax of most high-level programming languages allows for a string, usually quoted in some way, to represent an instance of a string datatype; such a meta ...

| | | | | EBCDIC: Encyclopedia II - G - History The letter G was created by the Romans because they felt that C was not an adequate letter to represent both /k/ and /g/.
The alleged inventor is a known historical figure, Spurius Carvilius Ruga (who flourished around 230 BC). G, which at this time took the place in the alphabet formerly held by Z, came to represent the sound /g/. As the sound /k/ did, /g/ also developed palatal and velar allophones which is why today, G has different sound values in all Romance languages, as well as Engli ...

System/360 - A family of computers.
Unlike past practice, IBM created an entire line of computers (or CPUs) from small to large, low to high performance, all running the same command set (with two exceptions for specific markets). This feat allowed customers to use a lower cost model and then upgrade to larger systems as their needs grew — without the time and expense of rewriting software. Many models (e.g. the 360/30) even offered the option of microcode emulation of the customer's previous computer (e.g. the IBM 1401 or the IBM 1620) s ...

| | | | | EBCDIC: Encyclopedia II - C - Phonetic use /k/ developed palatal and velar allophones in Latin, probably due to Etruscan influence. The Romance languages and English have a common feature inherited from Vulgar Latin where C takes on either a "hard" or "soft" value depending on the following vowel. In English and French, C takes the "hard" value /k/ finally and before A, O, and U, and the "soft" value /s/ before E, I, or Y. Romance languages obey similar rules, but the soft valu ...
