E (PC DOS)
E is the text editor which was made part of PC DOS with version 6.1 in June 1993, in February 1995 with version 7 and later with PC DOS 2000. In version 6.1, IBM dropped QBASIC, which, in its edit mode, was also the system text editor. It was necessary to provide some sort of editor, so IBM chose to adapt and substantially extend its OS/2 System Editor (1986), a minimally functional member of the E family of Editors. The DOS version is extended with a wide array of functions that are usually associated with more functional versions of the E editor family (see below). In version 7, IBM added the REXX language to DOS, restoring programmability to the basic box. IBM also provided E with OS/2. Features The features include (for PC DOS 7): *online help *edit large text files *draw boxes around text *mouse and menu support *record and play keystroke macros *change case within a marked area *access multiple files in multiple panes *syntax-directed editing of C and REXX *add and mult ...

DOSBox
DOSBox is a free and open-source MS-DOS emulator. It supports running programs primarily video games that are otherwise inaccessible since hardware for running a compatible disk operating system (DOS) is obsolete and generally unavailable today. It was first released in 2002, when DOS technology was becoming obsolete. Its adoption for running DOS games is relatively widespread; partially driven by its use in commercial re-releases of games. Development Before Windows XP, consumer-oriented versions of Windows were based on MS-DOS. Windows 3.0 and its updates were operating environments that ran on top of MS-DOS, and the Windows 9x series consisted of operating systems that were still based on MS-DOS. These versions of Windows could run DOS applications. Conversely, the Windows NT operating systems were not based on DOS. A member of the series, Windows XP, debuted on October 25, 2001, and became the first consumer-oriented version of Windows to not use DOS. Althou ...

DOS Commands
DOS (, ) is a family of disk-based operating systems for IBM PC compatible computers. The DOS family primarily consists of IBM PC DOS and a rebranded version, Microsoft's MS-DOS, both of which were introduced in 1981. Later compatible systems from other manufacturers include DR-DOS (1988), ROM-DOS (1989), PTS-DOS (1993), and FreeDOS (1994). MS-DOS dominated the IBM PC compatible market between 1981 and 1995. Although the name has come to be identified specifically with MS-DOS and compatible operating systems, ''DOS'' is a platform-independent acronym for ''disk operating system'', whose use predates the IBM PC. Dozens of other operating systems also use the acronym, beginning with the mainframe DOS/360 from 1966. Others include Apple DOS, Apple ProDOS, Atari DOS, Commodore DOS, TRSDOS, and AmigaDOS. History Origins IBM PC DOS (and the separately sold MS-DOS) and its predecessor, 86-DOS, ran on Intel 8086 16-bit processors. It was developed to be similar to Di ...

MS-DOS Editor
MS-DOS Editor, commonly just called edit or edit.com, is a TUI text editor. Originally, it was a 16-bit that shipped with MS-DOS 5.0 and later, as well as all 32-bit x86 versions of Windows. It supersedes edlin, the standard editor in earlier versions of MS-DOS. Originally, EDIT.COM was a stub that ran QBasic in editor mode. Starting with Windows 95, MS-DOS Editor became a standalone program because QBasic didn't ship with Windows. In 2025, Microsoft released a free and open-source remake. Overview Original The Editor version 1.0 appeared in MS-DOS 5.00, IBM PC DOS 5.0, OS/2, and Windows NT 4.0. This version relies on QBasic 1.0. Hence, it uses a text-based user interface (TUI), and its color scheme can be adjusted. It can only open one file, but can open the quick help file in a split window. The Editor version 1.1 appeared in MS-DOS 6.0. It uses QBasic 1.1 but no new features were added to the Editor. IBM PC DOS 6 dropped the Editor in favor of another text editor calle ...

IBM Generalized Markup Language
Generalized Markup Language (GML) is a set of macros that implement intent-based (procedural) markup tags for the IBM text formatter, SCRIPT. SCRIPT/VS is the main component of IBM's Document Composition Facility (DCF). A ''starter set'' of tags in GML is provided with the DCF product. Characteristics GML was developed in 1969 and the early 1970s by Charles Goldfarb, Edward Mosher and Raymond Lorie (whose surname initials were used by Goldfarb to make up the term GML). Using GML, a document is marked up with tags that define what the text is, in terms of paragraphs, headers, lists, tables, and so forth. The document can then be automatically formatted for various devices. For example, it is possible to format a document for a laser printer or a line (dot matrix) printer or for a screen by specifying a profile for the device, without changing the document itself. The Standard Generalized Markup Language (SGML), an ISO-standard technology for defining generalized markup ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Personal Editor
Personal Editor (PE) and Personal Editor II (PE2) was a text editor developed by IBM for IBM PC DOS and MS-DOS in the 1980s. It became popular because of its easy, fast, and programmable (custom keyboard shortcuts) user interface. PE influenced its successor text editors, such as Personal Editor 32, a modern 32-bit editor with a user interface based on PE2, and QE, a text editor for Linux systems.Personal Editor 3(PE3) is an open source implementation for 64 bit Linux and Windows 10+ running Intel compatible processors, implemented using thSNOBOL5programming language. For Asia-Pacific region, IBM Japan released a DBCS version of Personal Editor for IBM 5550 and PS/55. It was available in IBM's lineup over the years, although the E editor came with PC DOS since version 6.1.

NTVDM
Virtual DOS machines (VDM) refer to a technology that allows running 16-bit/32-bit DOS and 16-bit Windows programs when there is already another operating system running and controlling the hardware. Overview Virtual DOS machines can operate either exclusively through typical software emulation methods (e.g. dynamic recompilation) or can rely on the virtual 8086 mode of the Intel 80386 processor, which allows real mode 8086 software to run in a controlled environment by catching all operations which involve accessing protected hardware and forwarding them to the normal operating system (as exceptions). The operating system can then perform an emulation and resume the execution of the DOS software. VDMs generally also implement support for running 16-bit and 32-bit protected mode software ( DOS extenders), which has to conform to the DOS Protected Mode Interface (DPMI). When a DOS program running inside a VDM needs to access a peripheral, Windows will either allow this di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DOSEMU
DOSEMU, stylized as dosemu, is a compatibility layer software package that enables DOS operating systems (e.g., MS-DOS, DR-DOS, FreeDOS) and application software to run atop Linux on x86-based PCs (IBM PC compatible computers). Features It uses a combination of hardware-assisted virtualization features and high-level emulation. It can thus achieve nearly native speed for 8086-compatible DOS operating systems and applications on x86 compatible processors, and for DOS Protected Mode Interface (DPMI) applications on x86 compatible processors as well as on x86-64 processors. DOSEMU includes an 8086 processor emulator for use with real-mode applications in x86-64 long mode. DOSEMU is only available for x86 and x86-64 Linux systems (Linux 3.15 x86-64 systems cannot enter DPMI by default. This is fixed in 3.16). 140715 bugs.debian.org DOSEMU is an option for people who need or want to continue to use legacy DOS software; in some cases virtualisation is good enough to drive exter ...

Cross-platform Virtualization
Cross-platform virtualization is a form of computer virtualization that allows software compiled for a specific instruction set and operating system to run unmodified on computers with different CPUs and/or operating systems, through a combination of dynamic binary translation and operating system call mapping. Since the software runs on a virtualized equivalent of the original computer, it does not require recompilation or porting, thus saving time and development resources. However, the processing overhead of binary translation and call mapping imposes a performance penalty, when compared to natively-compiled software. For this reason, cross-platform virtualization may be used as a temporary solution until resources are available to port the software. Alternatively, cross-platform virtualization may be used to support legacy code, which running on a newer and faster machine still maintains adequate performance even with virtualization overhead.

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

OS/2
OS/2 is a Proprietary software, proprietary computer operating system for x86 and PowerPC based personal computers. It was created and initially developed jointly by IBM and Microsoft, under the leadership of IBM software designer Ed Iacobucci, intended as a replacement for DOS. The first version was released in 1987. A feud between the two companies beginning in 1990 led to Microsoft’s leaving development solely to IBM, which continued development on its own. OS/2 Warp 4 in 1996 was the last major upgrade, after which IBM slowly halted the product as it failed to compete against Microsoft's Microsoft Windows, Windows; updated versions of OS/2 were released by IBM until 2001. The name stands for "Operating System/2", because it was introduced as part of the same generation change release as IBM's "IBM Personal System/2, Personal System/2 (PS/2)" line of second-generation PCs. OS/2 was intended as a protected mode, protected-mode successor of IBM PC DOS, PC DOS targeting t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
