As the popularity of BASIC grew in this period, computer magazines published complete source code in BASIC for video games, utilities, and other programs. Given BASIC's straightforward nature, it was a simple matter to type in the code from the magazine and execute the program. Different magazines were published featuring programs for specific ...
The extended 8 KB version was then generalized into BASIC-80 (8080/85, Z80), and ported into BASIC-68 , BASIC-69 , and 6502-BASIC. The 6502 had somewhat less dense assembler code and expanded in size to just under 8K for the single precision version, or 9K for a version using an intermediate 40-bit floating point format in place of the original ...
As was the case in earlier BASICs, data types in Full were denoted by suffixes on the variable name. Minimal had avoided this issue by only having numeric variables, but Full included strings as well, denoted using the dollar-sign, for instance A$. [27] Full BASIC required decimal math for the default implementation of the floating point system
First implemented as a compile-and-go system rather than an interpreter, BASIC emerged as part of a wider movement towards time-sharing systems. General Electric, having worked on the Dartmouth Time-Sharing System and its associated Dartmouth BASIC, wrote their own underlying operating system and launched an online time-sharing system known as Mark I featuring a BASIC compiler (not an ...
Terminal for a MAI Basic/Four minicomputer. Basic/Four is a variety of Business Basic which originally ran on computers of the same name introduced in 1971. The company that produced the system, Management Assistance, Inc., was later known as Basic/Four Corporation, MAI Basic Four, Inc., and MAI Basic Four Information Systems.
GW-BASIC 3.20 (1986) adds EGA graphics support (no version of BASICA or GW-BASIC had VGA support) and is the last major new version released before it was superseded by QBasic. Buyers of Hercules Graphics Cards received a special version of GW-BASIC on the card's utility disk that is called HBASIC, which adds support for its 720×348 monochrome ...
The IBM Personal Computer BASIC, commonly shortened to IBM BASIC, is a programming language first released by IBM with the IBM Personal Computer, Model 5150 (IBM PC) in 1981. IBM released four different versions of the Microsoft BASIC interpreter , licensed from Microsoft for the PC and PCjr .
The ABC 80 was based on an earlier modular computer system from the same company [5] and built around a Z80 and 16 KB of ROM containing a fast semi-compiling BASIC interpreter. It had 16–32 KB of RAM as main memory and a dedicated (included) tape recorder for program and data storage, but could also be expanded to handle disk drives as well ...
