Editing Hexspeak (section)

== Alternative letters ==
Many computer languages require that a hexadecimal number be marked with a prefix or suffix (or both) to identify it as a number. Sometimes the prefix or suffix is used as part of the word.
* The [[C (programming language)|C programming language]] uses the "0x" prefix to indicate a hexadecimal number, but the "0x" is usually ignored when people read such values as words. C also allows the suffix L to declare an integer as <code>long</code>, or LL to declare it as <code>long long</code>, making it possible to write "0xDEADCELL" (dead cell). In either case a U may also appear in the suffix to declare the integer as <code>unsigned</code>, making it possible to write "0xFEEDBULL" (feed bull).
* In the (non-Unix) [[x86-assembly|Intel assembly language]], hexadecimal numbers are denoted by a "h" suffix, making it possible to write "0beach" (beach). Note that numbers in this notation that begin with a letter must be prefixed with a zero to distinguish them from variable names. A Unix-style assembler uses C language convention instead (but non-Unix-style assemblers are also available on x86 Unix-type OSes).
* [[Visual Basic]] and all previous Microsoft BASICs such as QuickBasic, GWBasic, BASICA and ColorBASIC, use a &H prefix, for example, "&HEADED" (headed) and "&HADC0FFEE" (had coffee).
* In Pascal and several [[assembly language]]s ([[6502]],[[6809]],...), hexadecimal numbers are denoted by a "$" prefix. This allows for words starting with the letter "S", for example "$EED" (seed).
* In [[Elektronika B3-34|B3-34]] [[programmable calculator]]s, an alternative hexadecimal alphabet was used, where the symbols "−", "L", "C", "Г", "E", and "&nbsp;" (space) were used instead of Latin letters. Using these, it was possible to display messages like "EГГ0Г" (error).
