- CONFIG
- OS/2 Command
-
- Ray Duncan
- September 12, 1989 (Utilities)
-
-
- Purpose: A full-screen editor for inspecting and modifying the
- directives contained in an OS/2 CONFIG.SYS file.
-
- Format: CONFIG [pathname]
-
- Remarks: The optional pathname parameter may be specified if the OS/2
- CONFIG.SYS file is located other than in the root directory of the boot drive.
- CONFIG.EXE will exit if the file is not found or if its read-only attribute is
- set.
-
- Entry into and exit from CONFIG.EXE are always made from its browse
- mode. When exiting, pressing Esc discards any changes made during the session;
- pressing X (eXit) saves a modified CONFIG.SYS file and renames the previous
- CONFIG.SYS with a .BAK extension. Confirming prompts are used with all crucial
- actions.
-
- In browse mode, the entire line is highlighted in reverse video, and
- movement through the CONFIG.SYS file is made with the Uparrow, DownArrow, PgUp,
- PgDn, Home, and End keys. Pressing D will delete an entire line and pressing R
- will restore it in this mode.
-
- Edit mode is entered by pressing either A (Add line at end of file), C
- (Change current line), or I (Insert line before current line). In edit mode,
- either the name field or the value field is highlighted and available for
- modification. In the directive PRIORITY=DYNAMIC, for example, PRIORITY is the
- name and DYNAMIC is the value. The Tab and Shift-Tab keys toggle between the
- two fields.
-
- When editing the name field, the UpArrow and DownArrow keys cycle
- through an alphabetical listing of all valid directives. No other entries can
- be made in this field. In the value field, however, CONFIG.EXE becomes a normal
- editor, with insert and overstrike modes toggled by the Ins key. Character
- deletions are made with the Del key, and Ctrl-End deletes to the end of the
- line. The Backspace key deletes the character under the cursor in insert mode
- and replaces it with a blank in overstrike mode. Cursor motion within a line is
- made with the Left and Right Arrow keys, Home, and End. Press Enter to accept,
- or Escape to discard changes made to a line and return to browse mode.
-
- Note: CONFIG.EXE and CONFIG.C, its source code file (written in
- Microsoft C, Version 5.1), may be downloaded from PC MagNet. The CONFIG.C
- source file printed with the article is a shortened form that omits on-line help
- and syntax checking for each directive.
