Forth

Forth,

river, c.60 mi (100 km) long, formed by streams that join near Aberfoyle in Stirling, S central Scotland. It meanders generally eastward past the town of Stirling to the Firth of Forth at Alloa. Its chief tributaries are the Teith and Allan rivers. The Firth of Forth extends c.55 mi (90 km) E from Alloa to the North Sea, reaching widths up to 19 mi (31 km) across. Rosyth is an important naval base, and LeithLeith

Rivers flowing into the firth include the Leven, Esk, Avon, and Carron. The Isle of May and Bass Rock, with lighthouses and ruins, are at the entrance to the firth; Inchkeith and Inchcolm islands are within the firth. At Queensferry three bridges cross the firth: the Forth Bridge, also known as Forth Railway Bridge (5,350 ft/1,631 m; completed 1890), the world's first cantilever bridge; the Forth Road Bridge, one of the longest suspension bridges in Europe (3,300 ft/1,006 m long; completed 1964); and the Queensferry Crossing, a cable-stayed road bridge (8,858 ft/2,700 m long; completed 2017). Two more bridges cross the firth farther inland, at or near Kincardine.

Forth

[fȯrth] (computer science) A high-level programming language developed primarily for microcomputers and characterized by a number of features that make it highly adaptable and readily extensible, such as the ability to be used as an interpreter or an operating system.

FORTH

(language)An interactive extensible language usingpostfix syntax and a data stack, developed by CharlesH. Moore in the 1960s. FORTH is highly user-configurable andthere are many different implementations, the followingdescription is of a typical default configuration.

Forth programs are structured as lists of "words" - FORTH'sterm which encompasses language keywords, primitives anduser-defined subroutines. Forth takes the idea ofsubroutines to an extreme - nearly everything is a subroutine.A word is any string of characters except the separator whichdefaults to space. Numbers are treated specially. Words areread one at a time from the input stream and either executedimmediately ("interpretive execution") or compiled as part ofthe definition of a new word.

The sequential nature of list execution and the implicit useof the data stack (numbers appearing in the lists are pushedto the stack as they are encountered) imply postfix syntax.Although postfix notation is initially difficult, experiencedusers find it simple and efficient.

Words appearing in executable lists may be "primitives"(simple assembly language operations), names of previouslycompiled procedures or other special words. A proceduredefinition is introduced by ":" and ended with ";" and iscompiled as it is read.

Most Forth dialects include the source language structuresBEGIN-AGAIN, BEGIN-WHILE-REPEAT, BEGIN-UNTIL, DO-LOOP, andIF-ELSE-THEN, and others can be added by the user. These are"compiling structures" which may only occur in a proceduredefinition.

FORTH can include in-line assembly language between "CODE"and "ENDCODE" or similar constructs. Forth primitives arewritten entirely in assembly language, secondaries contain amixture. In fact code in-lining is the basis of compilationin some implementations.

Once assembled, primitives are used exactly like other words.A significant difference in behaviour can arise, however, fromthe fact that primitives end with a jump to "NEXT", the entrypoint of some code called the sequencer, whereasnon-primitives end with the address of the "EXIT" primitive.The EXIT code includes the scheduler in some multi-taskingsystems so a process can be descheduled after executing anon-primitive, but not after a primitive.

Forth implementations differ widely. Implementationtechniques include threaded code, dedicated Forthprocessors, macros at various levels, or interpreterswritten in another language such as C. Some implementationsprovide real-time response, user-defined data structures,multitasking, floating-point arithmetic, and/or virtual memory.

Some Forth systems support virtual memory without specifichardware support like MMUs. However, Forth virtual memoryis usually only a sort of extended data space and does notusually support executable code.

FORTH does not distinguish between operating system callsand the language. Commands relating to I/O, file systemsand virtual memory are part of the same language as thewords for arithmetic, memory access, loops, IF statements, andthe user's application.

Many Forth systems provide user-declared "vocabularies" whichallow the same word to have different meanings in differentcontexts. Within one vocabulary, re-defining a word causesthe previous definition to be hidden from the interpreter (andtherefore the compiler), but not from previous definitions.

FORTH was first used to guide the telescope at NRAO, KittPeak. Moore considered it to be a fourth-generation language but his operating system wouldn't let him use sixletters in a program name, so FOURTH became FORTH.

Versions include fig-FORTH, FORTH 79 and FORTH 83.

FORTH

(FOuRTH-generation language) A high-level programming language created by Charles Moore in the late 1960s as a way of providing direct control of the computer. Resembling LISP syntax, FORTH uses reverse polish notation for calculations, and it is noted for its extensibility.

It is both compiler and interpreter. The source program is compiled first and then executed by its operating system/interpreter. It is used in process control applications that must quickly process data acquired from instruments and sensors. It is also used in arcade game programming as well as robotics and other AI applications. The following polyFORTH example converts Fahrenheit to Celsius:

 : CNV ( n) 32 - 5 9 * / . ." Celsius : user_input ." Enter Fahrenheit " CNV ;
