Looks to me like you are describing the C language. From the wikipedia
article:

http://en.wikipedia.org/wiki/C_%28programming_language%29

	[C] was designed to be compiled using a relatively
	straightforward compiler, to provide low-level access to
	memory, to provide language constructs that map efficiently to
	machine instructions, and to require minimal run-time support.
	C was therefore useful for many applications that had formerly
	been coded in assembly language, such as in system programming.

	Despite its low-level capabilities, the language was designed to
	encourage cross-platform programming. A standards-compliant and
	portably written C program can be compiled for a very wide
	variety of computer platforms and operating systems with few
	changes to its source code.

Exactly.
