E is the text editor which was made part of PC DOS with version 6.1 in June 1993, and later with version 7 and 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),〔(【引用サイトリンク】 url = http://evolutionarymedia.com/davis/resume/software.htm#os2sysed )〕 a minimally functional member of the E family of Editors.〔(【引用サイトリンク】 url = http://evolutionarymedia.com/davis/resume/software.htm#efamily )〕 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 multiply numbers in a marked area *locate and make a change globally within a file *select text and move, copy, overlay, or delete it *copy and move text from one file into another file E for PC DOS consists of five files: * E.EXE -- the executable program itself, (v3.13 in PC DOS 7)* E.EX -- pre-compiled profile for E's behavior* E.INI -- text file allowing modification of a few E.EX defaults (Not in v 3.12 (dos 6))* EHELP.HLP -- text file used for E's F1 key help in Browse (read-only) mode* BROWSE.COM -- loads a file into E in read-only mode. (Not in v 3.12 (dos 6))Since no tool was provided for building other profiles besides the supplied E.EX, PC DOS users have limited access to the full extensibility offered by the version 3 of E (e3) available to IBM programmers themselves. Still, it is a powerful implementation, with many features supporting the needs of general programmers.For PC DOS owners who have moved on to other operating systems, E can be run with the use of a DOS emulator (e.g. DOSBox) or with DOS virtualization software (e.g. DOSEMU or NTVDM). E runs quite successfully under the Windows NT 32-bit DOS prompt, for example. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「E (PC DOS)」の詳細全文を読む スポンサード リンク
