Therefore to substitute a line, a new line with the same number was written in the command line. At the same time that IBM released BASCOM 2.0 in 1985, Microsoft offered an almost identical interpreter as QuickBasic 1.0, only without the ISAM file handler. Compared to Basic interpreters available then, BASCOM 1.0 offered many additional capabilities and an enormous increase in programme execution speed. Examples of strong dialects are QuickBasic, QBasic, Basic PDS or Visual Basic, all by Microsoft Corporation. XML contains mark-up commands (also called tags or symbols) to describe the content and formatting of a page, but unlike HTML, the mark-up commands are unlimited and self-defining (therefore, designers can create their own customised commands and command definitions). Dartmouth Basic 1 of May 1964, 15 commands, 9 arithmetic or trigonometric functions, 15 symbols for arithmetic, logic or grouping operations, and 286 variables. Chronology of Basic: -Early 1964: Dartmouth Card Basic becomes available to Dartmouth members. 1970: Dartmouth Basic 5 becomes available to Dartmouth members. This command would be INPUT, which was introduced in Dartmouth Basic 3 of 1966. Also, if READ could not see any more DATA to be read, it considered the programme ended.

Although this meant that a programme written in Microsoft Basic could now call subroutines written in any of the other Microsoft languages, it also meant that IEEE mathematics was no longer an option, it became mandatory. Both the Microsoft and IEEE methods for storing single and double precision numbers use respectively 32 bits and 64 vbits, but the bits are organised differently. Popularly, billiards just use 3 balls: one red ball, white one with spot, and white without spot. A converted Victorian terrace guarded by a large, loud and lethal-looking Alsatian was pleasant enough but no one would put it on a par with The Crucible. Most students had some acquaintance with Basic, enough for being able to write some small programmes for their own personal purposes, mostly recreational or as a help in their other studies. Non-technical students were in this manner able to write their own programmes. The QBX interpreter uses expanded memory to store subprogrammes or functions, thus much larger programmes could be developed without resorting to editing and translating outside of the environment.

The editor was especially welcome because it allowed programmes to be written and tested very rapidly. Other features of this dialect were a utility programme to create custom run-time libraries, and a copy of the Microsoft programmer's Editor. The Microsoft editor has not been very accepted by many Basic programmers, mostly because it is big, slow and of complicated use. From about 1975 to about 1995 Basic was ubiquitous in one dialect or another. 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. The second dialect, now called Dartmouth Basic 1, was an interactive dialect for the Time Sharing System, what is billiards a number of dumb terminals that shared a common mainframe computer available at Darmouth. John Kemeny and John McGeachie declared in an interview in 1974, that at 04 hours (Official Local Time) of 1st May 1964 they had successfully executed the first interactive Basic programme from terminals of the Dartmouth Time Sharing System. Quick Libraries also helped to launch the start of a new class of Basic product: third-party add-on libraries. The environment was further enhanced with the advent of Quick Libraries, which allowed assembly language subroutines to be easily added to a Basic programme.

In 1994 Microsoft released Visual Basic for DOS. Because far strings are stored in a separate "far" area of DOS memory, it takes slightly longer to access those strings. With named subroutines, programmers were finally able to exceed the size limitation of 64 Kilobytes by writing separate modules that could then be linked together. 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. Continue from the next number, the 7, and eliminate its multiples. Start from the first number, the 2, and eliminate its multiples. They were usually numbered in intervals of ten or another number, thus making it possible to insert new lines without need of numbering all lines again. There was no need to log out, if human operators did not respond in a short time, they were automatically logged out by the Dartmouth Time Sharing System.
