This algorithm makes it easier to use SNOBOL as a logic programming language than is the case for most languages.

Originally programmed in SNOBOL for OS / 360 ; subsequently rewritten in C for Unix ( used diff for comparing files ).

* SNOBOL, an interpreter used for string processing

It was originally developed in SNOBOL at Bell Labs in 1972 by Marc J. Rochkind for an IBM System / 370 computer running OS / 360 MVT.

The initial SNOBOL language was created as a tool to be used by its authors to work with the symbolic manipulation of polynomials.

SNOBOL was the outcome ; it was a radically different language in its time and still is.

In many ways Icon also shares features with most scripting programming languages ( as well as SNOBOL and SL5, from which they were taken ): variables do not have to be declared, types are cast automatically, and numbers can be converted to strings and back automatically.

SNOBOL ( StriNg Oriented and symBOlic Language ) is a series of computer programming languages developed between 1962 and 1967 at AT & T Bell Laboratories by David J. Farber, Ralph E. Griswold and Ivan P. Polonsky, culminating in SNOBOL4.

Although SNOBOL itself has no structured programming features,

Because some users of the Python programming language found the use of regular expressions limiting, an extension to Python has been introduced, which makes it possible to use SNOBOL pattern matching in Python programs.

Early programming languages with pattern matching constructs include SNOBOL from 1962, SASL from 1976, NPL from 1977, and KRC from 1981.

Dr. Farber graduated from the Stevens Institute of Technology in 1956 and began an 11-year career at Bell Laboratories, where he helped design the first electronic switching system ( ESS-1 ) and the SNOBOL programming languages.

Snowball is a small string-handling programming language whose name was chosen as a tribute to the SNOBOL programming language, with which it shares the concept of string patterns delivering signals that are used to control the flow of the program.

In an amusing coincidence, the SNOBOL programming language was originally named SEXI-String EXpression Interpreter.

The player in the role of Tron has to beat four subgames, each at 12 increasingly difficult levels, with each level named after a computer programming language, such as " BASIC ", " RPG ", " COBOL ", " FORTRAN ", " SNOBOL ", " PL1 ", " PASCAL ", " ALGOL ", " ASSEMBLY ", " OS ", " JCL " and " User ", ( then " User " repeats itself ).

With interpreted languages, the " machine code " is the source text and may be susceptible to editing on-the-fly: in SNOBOL the source statements being executed are elements of a text array.

One of the designers of SNOBOL, Ralph Griswold, designed successors to SNOBOL4 called SL5 and Icon, which combined the backtracking of SNOBOL4 pattern matching with more standard ALGOL-like structuring, as well as adding some features of their own.

Complex SNOBOL patterns can do things that would be impractical or impossible using the more primitive regular expressions used in most other pattern matching languages.

It is related to SNOBOL and SL5, string processing languages.

All of us yelled at once, " WE GOT IT -- SNOBOL " in the spirit of all the BOL languages.

As a language, XSLT is influenced by functional languages, and by text-based pattern matching languages in the tradition of SNOBOL and awk.

In 2012, iProDeveloper author Mel Beckman suggested that RPG should be considered a dead language, along with ALGOL, BAL, BASIC, PL / I, and SNOBOL.

The keywords are, from lowest difficulty to highest: RPG, COBOL, BASIC, FORTRAN, SNOBOL, PL1, PASCAL, ALGOL, ASSEMBLY, OS, JCL, USER.

However the macro features of the assembler were used to define the virtual machine instructions of the SNOBOL Implementation Language, the SIL.

A SNOBOL pattern can be very simple or extremely complex.

It is possible to implement a language interpreter in SNOBOL almost directly from a Backus-Naur form expression of it, with few changes.

Some of this power derives from the so-called " SPITBOL extensions " ( which have since been incorporated in basically all modern implementations of the original SNOBOL 4 language too ), although it is possible to achieve the same power without them.

SNOBOL stores variables, strings and data structures in a single garbage-collected heap.

The pioneer string-processing language SNOBOL ( 1962 ) may have been the first to provide a built-in general backtracking facility.

They were inseparable, not because they were fond of each other, but because they wanted to keep an eye on each other, as they were keen rivals for social leadership.

Zeus and Poseidon had been rivals for the hand of Thetis until Prometheus, the fore-thinker, warned Zeus of a prophecy that Thetis would bear a son greater than his father.

That Olynthus was backed by Athens and Thebes, rivals to Sparta for the control of Greece, provided them with an additional incentive to break up this growing power in the north.

He resolved to suppress many abuses, but above all things, to check feudalism and limit the power of the nobles, who were rivals for his throne.

Although not as well supported by the biggest software publishers as rivals like the Commodore 64 and Sinclair ZX Spectrum, a good range of games were available for the Electron.

However, even with Mozart and Salieri being rivals for certain jobs, there is very little evidence that the relationship between the two composers was at all acrimonious beyond this, especially after 1785 or so when Mozart had become established in Vienna.

When the Sequani, their hereditary rivals, with the assistance of a Germanic chieftain named Ariovistus defeated and massacred the Aedui at the Battle of Magetobriga, the Aedui sent Diviciacus, the druid, to Rome to appeal to the senate for help.

Louis VI of France convened a national council of the French bishops at Étampes in 1130, and Bernard was chosen to judge between the rivals for pope.

Another recurring gag was for other characters to mispronounce his name, often, particularly in the case of rivals, deliberately.

The best argument for rule-consequentialism is that it does a better job than its rivals of matching and tying together our moral convictions, as well as offering us help with our moral disagreements and uncertainties "

Despite this, Chicago engaged St. Louis in a see-saw battle for first place into August, but the Cardinals played to a torrid 20 – 6 pace that month, designating their rivals to battle in the Wild Card race, from which they were eliminated in the season's final week.

The Great Army defeated an attack on York by the two rivals for the Northumbrian throne, Osberht and Ælla, who had put aside their differences in the face of a common enemy.

In World War II rivals who had combat service in the first great war ( led by Gen. Bernard Montgomery ) sought to denigrate Eisenhower for his previous lack of combat duty, despite his stateside experience establishing a camp, completely equipped, for thousands of troops, and developing a full combat training schedule.

The immediate necessity for the Labours of Heracles is as penance for Heracles ' murder of his own family, in a fit of madness, which had been sent by Hera ; however, further human rather than mythic motivation is supplied by mythographers who note that their respective families had been rivals for the throne of Mycenae.

Essendon would win only three matches and draw one ( against wooden spoon contenders Carlton ) for the entire season, but one of those was against finals-bound rivals and arch-enemy Collingwood in round 19 in a win that would ultimately cost the Magpies a top four berth that season.

These included strikes against leading Jordanian politicians, as a means of exacting vengeance and raising the price for attacking the Palestinian movement ; and also, most controversially, for " international operations " ( e. g. the Munich Olympics attack ), intended both to put pressure on the US, European countries and Israel, and to raise the visibility of the Palestinian cause, and to upstage radical rivals such as the PFLP.

His final appearance was a 2 – 3 defeat away to local rivals Tampa Bay Rowdies on 17 June 1978, in which Rodney Marsh scored all three for the home team.

Following the short reign of Pertinax, several rivals for the emperorship emerged, including Septimius Severus and Clodius Albinus.

In order to maintain security, the province required the presence of three legions ; but command of these forces provided an ideal power base for ambitious rivals.
