Bluebird SuperDOS
Data General Business Basic was a BASIC interpreter (based on a version from MAI Basic Four) marketed by Data General for their Data General Nova, Nova minicomputer in the 1970s, and later ported to the Data General Data General Eclipse MV/8000, Eclipse MV and Aviion, AViiON computers. Most business applications for the Nova were developed in Business Basic. Description Business Basic was an integer-only language inspired by COBOL, and contained powerful string-handling functions and the ability to manipulate indexed files very quickly. It also provided full control over the display screen, with cursor positioning, attribute setting, and region-blanking commands. Business Basic could interface to Data General's INFOS II Database management system, database, and make calls directly to the operating system. A lock server gave multiple concurrent users efficient access to database records. Small business programs could be developed and debugged rapidly with Business Basic because ...

Operating System
An operating system (OS) is system software that manages computer hardware and software resources, and provides common daemon (computing), services for computer programs. Time-sharing operating systems scheduler (computing), schedule tasks for efficient use of the system and may also include accounting software for cost allocation of Scheduling (computing), processor time, mass storage, peripherals, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computerfrom cellular phones and video game consoles to web servers and supercomputers. , Android (operating system), Android is the most popular operating system with a 46% market share, followed ...

Unix
Unix (, ; trademarked as UNIX) is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others. Initially intended for use inside the Bell System, AT&T licensed Unix to outside parties in the late 1970s, leading to a variety of both academic and commercial Unix variants from vendors including University of California, Berkeley ( BSD), Microsoft (Xenix), Sun Microsystems ( SunOS/ Solaris), HP/ HPE ( HP-UX), and IBM ( AIX). The early versions of Unix—which are retrospectively referred to as " Research Unix"—ran on computers such as the PDP-11 and VAX; Unix was commonly used on minicomputers and mainframes from the 1970s onwards. It distinguished itself from its predecessors as the first portable operating system: almost the entire operating system is written in the C programming language (in 1973), which allows U ...

B32 Business Basic
B32 Business Basic was a competitor to Data General Business Basic written by Murray Haszard in 1986. It ran on the Data General Eclipse MV line of computers initially, and was ported to Unix in 1989 and to DOS in 1991. B32 Software was the company that developed and supported B32 Business Basic, with the original site in Auckland, New Zealand, supplemented by a sales and support centre in Blue Ash, Ohio. The B32 interpreter was highly compatible with Data General Business Basic (DGBB), but it also enhanced and extended that language in many ways. Like DGBB, B32 could access Data General's INFOS II database and it could use DGBB's lock server or its own improved version. B32 was over twice as fast for number crunching, string manipulation, and disk I/O. Many of the internal restrictions of DGBB were removed. B32 allowed 32,767 line numbers (65,535 in later versions), compared with DGBB's 9,999. B32 allowed more memory for programs, more simultaneous locks, and more files to be open ...

Bluebird Business Basic
The bluebirds are a North American group of medium-sized, mostly insectivorous or omnivorous passerine birds in the genus ''Sialia'' of the thrush family (Turdidae). Bluebirds are one of the few thrush genera in the Americas. Bluebirds lay an average of 4 to 6 eggs per clutch. They will usually brood two or three times in a year. Bluebirds nest from March all the way through August. Bluebirds have blue, or blue and rose beige, plumage. Female birds are less brightly colored than males, although color patterns are similar and there is no noticeable difference in size. Taxonomy and species The genus ''Sialia'' was introduced by the English naturalist William Swainson in 1827 with the eastern bluebird (''Sialia sialis'') as the type species. A molecular phylogenetic study using mitochondrial sequences published in 2005 found that ''Sialia'', ''Myadestes'' (solitaires) and ''Neocossyphus'' (African ant-thrushes) formed a basal clade in the family Turdidae. Within ''Sialia'' the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
16-bit
16-bit microcomputers are microcomputers that use 16-bit microprocessors. A 16-bit register can store 216 different values. The range of integer values that can be stored in 16 bits depends on the integer representation used. With the two most common representations, the range is 0 through 65,535 (216 − 1) for representation as an ( unsigned) binary number, and −32,768 (−1 × 215) through 32,767 (215 − 1) for representation as two's complement. Since 216 is 65,536, a processor with 16-bit memory addresses can directly access 64 KB (65,536 bytes) of byte-addressable memory. If a system uses segmentation with 16-bit segment offsets, more can be accessed. As of 2025, 16-bit microcontrollers cost well under a dollar (similar to close in price legacy 8-bit); the cheapest 16-bit microcontrollers cost less than other types including any 8-bit (and are more powerful, and easier to program generally), making 8-bit legacy microcontrollers not worth it for new applicatio ...

32-bit
In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in a maximum of 32- bit units. Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle. Typical 32-bit personal computers also have a 32-bit address bus, permitting up to 4 GiB of RAM to be accessed, far more than previous generations of system architecture allowed. 32-bit designs have been used since the earliest days of electronic computing, in experimental systems and then in large mainframe and minicomputer systems. The first hybrid 16/32-bit microprocessor, the Motorola 68000, was introduced in the late 1970s and used in systems such as the original Apple Macintosh. Fully 32-bit microprocessors such as the HP FOCUS, Motorola 68020 and Intel 80386 were launched in the early to mid 1980s and became dominant by the early 1990s. This gener ...

Self-modifying Code
In computer science, self-modifying code (SMC or SMoC) is source code, code that alters its own instruction (computer science), instructions while it is execution (computing), executing – usually to reduce the instruction path length and improve computer performance, performance or simply to reduce otherwise duplicate code, repetitively similar code, thus simplifying software maintenance, maintenance. The term is usually only applied to code where the self-modification is intentional, not in situations where code accidentally modifies itself due to an error such as a buffer overflow. Self-modifying code can involve overwriting existing instructions or generating new code at run time and transferring control to that code. Self-modification can be used as an alternative to the method of "flag setting" and conditional program branching, used primarily to reduce the number of times a condition needs to be tested. The method is frequently used for conditionally invoking test/deb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Structured Programming
Structured programming is a programming paradigm aimed at improving the clarity, quality, and development time of a computer program by making specific disciplined use of the structured control flow constructs of selection ( if/then/else) and repetition ( while and for), block structures, and subroutines. It emerged in the late 1950s with the appearance of the ALGOL 58 and ALGOL 60 programming languages, with the latter including support for block structures. Contributing factors to its popularity and widespread acceptance, at first in academia and later among practitioners, include the discovery of what is now known as the structured program theorem in 1966, and the publication of the influential " Go To Statement Considered Harmful" open letter in 1968 by Dutch computer scientist Edsger W. Dijkstra, who coined the term "structured programming". Structured programming is most frequently used with deviations that allow for clearer programs in some particular cases, such as whe ...

Debug
In engineering, debugging is the process of finding the root cause, workarounds, and possible fixes for bugs. For software, debugging tactics can involve interactive debugging, control flow analysis, log file analysis, monitoring at the application or system level, memory dumps, and profiling. Many programming languages and software development tools also offer programs to aid in debugging, known as debuggers. Etymology The term ''bug'', in the sense of defect, dates back at least to 1878 when Thomas Edison wrote "little faults and difficulties" in his inventions as "Bugs". A popular story from the 1940s is from Admiral Grace Hopper. While she was working on a Mark II computer at Harvard University, her associates discovered a moth stuck in a relay that impeded operation and wrote in a log book "First actual case of a bug being found". Although probably a joke, conflating the two meanings of bug (biological and defect), the story indicates that the term was used in t ...
