FORTH Definition/Meaning:
A programming language much in vogue among users of microcomputers. FORTH
operands are held on a stack, and programs take
the form of strings in reverse Polish notation. A vital feature of FORTH is that a symbol (a WORD) can
be associated with any program string, and such a user-defined word can then be
used in expressions on equal terms with the system words (operators). This makes
FORTH a flexible extensible language in which it is possible to define a
customized language for, say, the control of a scientific instrument. The FORTH
system is very compact; the interpreter and the dictionary containing the
system-defined words can be fitted into 8K bytes.
