World Pool Rules

5.13.1 - Pocketing Opponent’s Ball - It is a foul to pocket an opponent’s ball without also pocketing a ball from your own group. If the area referee is asked to determine whether a foul occurred and there is no evidence of the foul except the claim of one player while the other player claims that there was no foul, then it is assumed that no foul occurred. Each of the back corners should have a solid and stripe in them, while the eight ball is in the center. Snooker cues are about the same length as pool, though some have a slightly smaller tip. Programme statements could exceed 255 characters, a single string could have up to 32767 characters, and assembly language subroutines could be linked directly to a Basic programme. PHP: a server side scripting language commonly used to write programmes for Common Gateway Interface. Its distribution includes a compiler to produce executable programmes. Work on the Basic compiler and on a time sharing system at Darmouth College was done concurrently, therefore this first dialect of early 1964 was executed in the batch processing system before the time sharing system were ready.

Many non-technical human operators often believed that the commands were part of the Basic language, but in fact they were part of the Dartmouth Time Sharing System itself and were also used when preparing Algol or Fortran programmes via the Dartmouth Time Sharing System terminals. As opposed to a page (screen) editor, a line editor can only move the cursor horizontally, but not vertically (much like the COPY CON and similar commands that were later used in DOS and other operating systems of the 1970's and 1980's, or like the EDLIN text editor). Shortly later they signed a contract with the maker of Altair, Mister Edward Ted Roberts (Micro Instrumentation and Telemetry Systems) for the inclusion of that Basic dialect in the Read Only Memory of Altair units. Thus, the dialect is now known as Altair Basic. In one of the big computers of the Massachussetts Institute of Technology, they emulated the Intel 8080 microprocessor that had been incorporated in the Altair 8800 microcomputer. Basic was one of the very first programming languages intended to be used interactively, since Dartmouth Basic 1. Almost immediately Basic became so succesful that in October of its first year, 1964, some modification was done into it, thus making its third dialect now called Dartmouth Basic 2. Several dialects were produced over the years, all implemented as compilers by undergraduate teams working under the direction of the original designers.

Steve Garland modified Dartmouth Basic 6 to facilitate structured modular programming in connected blocks, in an effort to avert the abuse of line jumping by GOTO or GOSUB instructions that was a typical characteristic of sequential linear programming in a single block. Annother effort to facilitate structured modular programming in connected blocks, as opposed to sequential linear programming in a single block. This structured approach had been advocated by programming theorists such as Edsger Dijkstra, and it was strictly applied to some new languages, such as Pascal (1971). SBasic was a precompiler that produced Dartmouth Basic 6 output, and that formed the basis of ANSI Basic. Eliminate number 1. Although strictly speaking one is a prime number, it does not need to appear in the list of prime numbers because it is the start of numbering itself. The long search for a formula to find prime numbers has already lasted for over 2 500 years, without result.

Knowing prime numbers is useful for determining instantly the divisibility or not of a given number, without need of performing the operation of division. Continue from the next number, the 7, and eliminate its multiples. Start from the first number, the 2, and eliminate its multiples. Then the next, the 11. Then the next, the 13. Then the next, the 17. Every time eliminate the multiples of each of these numbers. The player must then pocket a numbered ball, what is billiards or cause the cue ball or any numbered ball to contact a rail. The cue ball may contact an object ball directly or it can be made to bounce off one or more cushions before hitting the required object ball. The spin is in the direction opposite from the "rolling" direction along the cushion during contact. It is the same as the amount of sidespin required for gearing outside spin. The best reference for billiard-related words, their origins and meanings, is Mike Shamos’ "New Illustrated Encyclopedia of Billiards." The earliest example found of the word "English" to mean side spin was in the New York Times in 1873. Shamos points out that the use of side spin was documented in 1806 which pre-dated the invention of the tip by Mingaud (about 1818). Chalk was also used before tips were invented.
