A procedural programming language without type checking, Forth features both interactive execution of commands ( making it suitable as a shell for systems that lack a more formal operating system ) and the ability to compile sequences of commands for later execution.

Other uses of Forth include the Open Firmware boot ROMs used by Apple, IBM, Sun, and OLPC XO-1 ; and the FICL-based first stage boot controller of the FreeBSD operating system.

Forth evolved from Charles H. Moore's personal programming system, which had been in continuous development since 1958.

Forth is so named because in 1968 " the file holding the interpreter was labeled FOURTH, for 4th ( next ) generation software — but the IBM 1130 operating system restricted file names to 5 characters.

A Forth system has often been used to bring up new hardware.

For example, Forth was the first resident software on the new Intel 8086 chip in 1978 and MacFORTH was the first resident development system for the first Apple Macintosh in 1984.

At least one home computer, the British Jupiter ACE, had Forth in its ROM-resident operating system.

The Canon Cat also used Forth for its system programming.

The ACE had an 8 KB ROM containing the Forth kernel and operating system, and the predefined dictionary of Forth words in about 5KB.

This decompiling ability had several advantages as a solution to the absence of the more flexible disk system used by Forth.

Television, along with most radio services, are broadcast to the city from the Craigkelly transmitting station situated on the opposite side of the Firth of Forth.

By including interaction, scripting, and compilation, Forth was popular on computers with limited resources, such as the BBC Micro and Apple II series, and remains so in applications such as firmware and small microcontrollers.

Forth has been used successfully in large, complex projects, while applications developed by competent, disciplined professionals have proven to be easily maintained on evolving hardware platforms over decades of use.

It has been implemented efficiently on modern RISC processors, and processors that use Forth as machine language have been produced.

Forth relies heavily on explicit use of a data stack and reverse Polish notation ( RPN or postfix notation ), commonly used in calculators from Hewlett-Packard.

ACE's Forth was based mostly on Forth-79, with some relevant differences.

This was followed by a second series, Blackadder II ( 1986 ) set during the reign of Elizabeth I, a third series Blackadder the Third ( 1987 ) set during the late 18th and early 19th centuries in the reign of George III, and finally Blackadder Goes Forth ( 1989 ) in 1917, set in the trenches of the Great War.

" Alarmed, James called for national fasting and public prayers, kept watch on the Firth of Forth for Anne ’ s arrival, wrote several songs, one comparing the situation to the plight of Hero and Leander, and sent a search party out for Anne, carrying a letter he had written to her in French: " Only to one who knows me as well as his own reflection in a glass could I express, my dearest love, the fears which I have experienced because of the contrary winds and violent storms since you embarked ...".

Later series ( Blackadder II, Blackadder the Third, Blackadder Goes Forth ) moved the duo through history and switched the relationship: the Edmund Blackadder of Blackadder II was a brilliant schemer, whereas Baldrick had devolved into a buffoon whose catchphrase was " I have a cunning plan " ( which he rarely had ).
