The SvarDOS editor (SVED) is designed for basic editing of configuration files
|
|
|
9 |
and such. It is NOT meant to be a full-featured text editor. On the pro side,
|
|
|
10 |
it has a low memory footprint and is only a couple kilobytes big, which makes
|
| 1411 |
mateusz.vi |
11 |
it a good fit for bootdisks and systems with extremely limited resources.
|
| 1344 |
mateusz.vi |
12 |
|
|
|
13 |
- runs comfortably on a 8086-class PC with 256 KiB of RAM
|
| 1447 |
mateusz.vi |
14 |
- auto-detects color and monochrome video modes
|
| 1440 |
mateusz.vi |
15 |
- supports unusual text modes like 80x43, 80x50, 40x25...
|
| 1344 |
mateusz.vi |
16 |
- multilingual UI
|
| 1431 |
mateusz.vi |
17 |
- only 7 KiB of disk footprint
|
| 1447 |
mateusz.vi |
18 |

|
| 1344 |
mateusz.vi |
19 |
- loads files larger than 64 KiB
|
| 1431 |
mateusz.vi |
20 |

|
| 1447 |
mateusz.vi |
21 |

|
| 1431 |

### USAGE AND KEY BINDINGS ###################################################
|
|
|
34 |
|
|
|
35 |
Navigation within the text file is achieved through the usual, standard keys:
|
|
|
36 |
- up, down, right and left arrows
|
|
|
37 |
- PageUp / PageDown
|
|
|
38 |
- Home / End
|
|
|
39 |
|
| 1410 |
mateusz.vi |
40 |
On top of these, the following key bindings are available:
|
| 1354 |
mateusz.vi |
41 |
|
| 1410 |
mateusz.vi |
42 |
ESC = access the program's menu
|
|
|
43 |
CTRL+RIGHT = jump to next word
|
|
|
44 |
CTRL+LEFT = jump to previous word
|
|
|
45 |
CTRL+C = copy the current line to clipboard
|
|
|
46 |
CTRL+X = cut the current line and move it to clipboard
|
|
|
47 |
CTRL+V = paste the clipboard content to current location
|
| 1354 |
mateusz.vi |
48 |
|
| 1366 |
mateusz.vi |
49 |
SVED can load up to 10 files simultaneously. To switch from one file to
|
| 1410 |
mateusz.vi |
50 |
another use the F1..F10 function keys (F1 = file 1, F2 = file 2, etc).

### MULTILINGUAL SUPPORT #####################################################
|
|
|
54 |
|
| 1397 |
mateusz.vi |
55 |
The LNG file contains non-english strings. It should be placed in the same
|
|
|
56 |
directory where the program's executable resides. The UI language is
|
| 1366 |
mateusz.vi |
57 |
controlled by the LANG environment variable, for example SET LANG=PL would
|
|
|
58 |
make it display polish strings.
|
|
|
59 |
|
| 1397 |
mateusz.vi |
60 |
If you rename the SVED.COM executable (for example to EDIT.COM), then you need
|
|
|
61 |
to rename the LNG file accordingly (for example to EDIT.LNG).
|
| 1366 |
mateusz.vi |
62 |
|
| 1397 |
mateusz.vi |
63 |
You can safely delete the LNG file if you do not need non-english UI and wish
|
|
|
64 |
to free some disk space.
