Editing Value (computer science) (section)

== In assembly language ==
A value can be virtually any kind of data by a given [[data type]], for instance a string, a digit, a single letter.

Processors often support more than one size of immediate data, e.g. 8 or 16 bit, employing a unique opcode and mnemonic for each instruction variant. If a programmer supplies a data value that will not fit, the assembler issues an "Out of range" error message. Most assemblers allow an immediate value to be expressed as [[ASCII]], [[decimal]], [[hexadecimal]], [[octal]], or [[Binary code|binary]] data. Thus, the ASCII character {{codett|'A'}} is the same as {{codett|65}} or {{codett|0x41}}. The [[byte order]] of strings may differ between processors, depending on the assembler and computer architecture.
