When the user is in file panel, at his occasionally the need in viewing/editing of any external viewer or editor arises. In Navigator the opportunity of viewing/editing of particular file is realized. Is realized through file of extensions (for viewer - dn.vwr, for editor - dn.edt).
This file has described work with particular file type, determined on DOS extension. For viewing/editing of file is necessary to be moved the cursor on file panel to name of this file and for viewing to press F3 and for Z
editing - Alt-F4 (if is installed in Options|Defaults|Configuration... Internal editor). W
For description of viewing of files it is necessary to cause command Options|Viewers. W
For description of editing of files it is necessary to cause command Options|Editors. ,
The format of record in this file is such:
???:command_name
Here ??? - particular extension :
Command_name - name of program for viewing or editing
DOS Wildcards
and Filters
DOS file names have two parts: the name (which can be up to 8 characters) and the extension (which can be up to 3 characters) with a period in between. For example, "filename.ext".
* Match any characters for the rest of the name or
extension. "a*" will match "a", "ab", and "abc", as
well as many others. '*' applies just to one part of
the file name, so "a*" will not match "ab.c". Use
"a*.*" to find all files that start with 'a' and have
any extension. (Note: "*a" will match any name, and
not just names with an `a' at the end as you might
expect.)
DOS Navigator allows not only single file masks, but containers of masks too. These containers are called "Filters". Filter is a file mask sequence in that every mask is separated by ";" char. '
E.g. : *.exe;*.com;*.bat;*.btm;*.cmd 4
*.asm;*.c;*.cpp;*.inc;*.pas are Filters
Customized
Video modes
DOS Navigator supports not only standard text modes. It is possible to use Super EGA, VGA and VESA BIOS extensions. If you want to use it, put in System configuration dialogue "Video mode 1" and "Video mode 2" codes of desired video modes. This codes must be described in technical documentation of your Video system.
Some of codes is known to me:
29 (132x25),30 (132x60) - for Realtek VGAs
84,85,86 - Trident VGAs
80,81,82 - OAK Technology VGAs
and most of Super EGA/VGAs.
If your video system is VESA compatible, you can use universal VESA mode codes (note that VESA XGA and VESA SVGA has different mode codes). These codes is greater than 256. For VESA SVGA codes are 267, 268, for example.
Note: Most of mouse drivers doesn't support extended
video modes. Therefore you must switch off
"Standard cursor" option in Mouse setup dialogue
if you get any ugly effects when moving mouse cursor
in non-standard video modes.
Hint: For VGA adaptors mode nomber 256 means mode 80x33.
OS/2 Support
NB: OS/2 is a registered trademark of IBM Corp.
DOS Navigator can start OS/2 applications when it works under OS/2 version 2.10 or later. To get this possibility you should:
1) Set OS2COMSPEC environment variable to full name
of OS/2 command interpreter
(e.g. put Set OS2COMSPEC = C:\OS2\CMD.EXE
in DOS session autoexec)
2) Set "OS/2 support" option in Startup dialog box.
3) Restart Navigator.
There are three ways to run OS/2 applications:
From DOS command line:
Put before command string one of chars listed below:
">" - run foreground Full Screen OS/2 session
"<" - run background Full Screen OS/2 session
"]" - run foreground Windowed OS/2 session
"[" - run background Windowed OS/2 session
Switch to OS/2 command prompt mode by Alt-/
Run executable files from file panel:
highlight required file and press
- Alt-Shift-Enter to run it foreground
- Alt-Ctrl-Enter to run background.
NB: in OS/2 command prompt mode all programs
include DOS applications starts in another
sessions. Be sure that parameters for DOS
sessions are acceptable for your applications.
Hints:
if Files Highlight and OS/2 support options
are enabled OS/2 batch files (*.CMD) are shown
as executable files. You can start it as usual
.EXE files by pressing Enter. If you'll press
Shift-Enter, batch will be started in background.
4DOS/Files.BBS support
Yes, DOS Navigator supports it!
It is possible by setting up Panel|Setup Columns - just set "Descriptions" checkbox on. Not only view descriptions is possible, but copying, moving and editting too! d
Copy/move file with its descriptions is possible only when descriptions are present in file panel.
If you want to edit file description (by Alt-INS key), but file with descriptions doesn't exists, Navigator will create file with first file name given in "Files with descriptions" line of File Panel Defaults dialog box.
