SvarCOM is the SvarDOS command line interpreter, known usually under the name
|
|
|
7 |
"COMMAND.COM". It is designed and maintained by Mateusz Viste, and distributed
|
|
|
8 |
under the terms of the MIT license.

SvarCOM is minimalist and I'd like to keep it that way. It aims to be
|
474 |
mateuszvis |
11 |
functionaly equivalent to COMMAND.COM from MS-DOS 5.x/6.x. No LFN support.

SvarCOM's resident footprint is under 2 KiB.

Translation strings are stored in the file SVARCOM.LNG, which should be
|
|
|
16 |
placed in a directory pointed at by %NLSPATH% for SvarCOM to be able to output
|
|
|
17 |
messages in non-english languages. SvarCOM's language is controlled by the
|
990 |
mateusz.vi |
18 |
%LANG% environment variable.

=== INSTALLATION =============================================================
|
|
|
61 |
|
|
|
62 |
Installing SvarCOM requires to either copy it to the root of your boot drive
|
|
|
63 |
replacing your current COMMAND.COM, or adding a SHELL directive to your
|
|
|
64 |
CONFIG.SYS file to instruct DOS that it should load SvarCOM as its shell, eg.:
|
|
|
65 |
|
638 |
mateusz.vi |
66 |
SHELL=C:\SVARCOM\COMMAND.COM /P
|
578 |
mateuszvis |
67 |
|
|
|
68 |
Some DOSes support a SHELLHIGH directive that loads the shell in high memory.
|
|
|
69 |
It is pointless to use it to load SvarCOM. SvarCOM will load its resident part
|
638 |
mateusz.vi |
70 |
as high as possible on its own, enforcing this through SHELLHIGH could even
|
|
|
71 |
be harmful since SvarCOM wouldn't be able to relocate to the highest address
|
|
|
72 |
as it would be allocated by SHELLHIGH already.
|
578 |
mateuszvis |
73 |
|
|
|
74 |
SvarCOM supports multiple languages. To enable SvarCOM using them it is
|
|
|
75 |
necessary to define an NLSPATH environment variable that would point to a
|
|
|
76 |
directory and copy the SVARCOM.LNG file there. Once done, SvarCOM will try
|
|
|
77 |
loading whatever language is being set up in the LANG environment variable.
