Operator overloading is syntactic sugar, and is used because it allows programming using notation nearer to the target domain [1] and allows user-defined types a similar level of syntactic support as types built into a language. It is common, for example, in scientific computing, where it allows computing representations of mathematical objects ...
In the real world some low-end devices may only support a subset of these 488.2 commands, or may even accept the commands but not perform any operation. A user should check the official programmers manual for each device before assuming all of these 488.2 commands are supported.
Most user guides contain both a written guide and associated images. In the case of computer applications, it is usual to include screenshots of the human-machine interface(s), and hardware manuals often include clear, simplified diagrams. The language used is matched to the intended audience, with jargon kept to a minimum or explained thoroughly.

Before Unix (e.g., GCOS), documentation was printed pages, available on the premises to users (staff, students...), organized into steel binders, locked together in one monolithic steel reading rack, bolted to a table or counter, with pages organized for modular information ...
The general, non-MediaWiki Lua reference manual can—while being very well written, comprehensive, and informative—be problematic for beginners, because certain features don't work in Wikipedia—beginning with print(), which appears in standard Lua "hello world" programs.
In computing, a programming language reference or language reference manual is part of the documentation associated with most mainstream programming languages. It is written for users and developers , and describes the basic elements of the language and how to use them in a program .
Front view of a Programma 101 showing the printer and programming keys. The Programma 101 can calculate the four basic arithmetic functions (addition, subtraction, multiplication, and division), plus square root, absolute value, and fractional part. It is equipped with memory registers with features such as clear, transfer, and exchange, plus ...
The FOCAL manual showed how to add commands to the FOCAL parser, so many sites added specialized commands for operating custom hardware. The Digital Equipment Computer Users' Society collected many patches and enhancements for FOCAL. There were even major enhanced offshoots of FOCAL, such as FOCAL-W, which added many features, including better ...
