CONFIG.SYS - SET Statements

From EDM2
Revision as of 02:12, 15 November 2017 by Martini (talk | contribs) (→PM_)

Return to The Config.sys Documentation Project Main Page

Environment variables are stored by OS/2 in memory and can be called by any program. They are used by many programs to store information (for example, the install path) or some configuration information. If you want to see a list of all installed environment variables and their values, type "Set" in an OS/2 window. If the list is too long, you can redirect the screen output to a file, simply type this: 

SET >output.txt

General Tips

Note that SET commands in CONFIG.SYS behave differently than when entered on the command line.

So, when you issue the following comands in a OS/2 session: 

SET TEMP=C:\TMP
SET TMP=%TEMP%

you get: 

TEMP=C:\TMP
TMP=C:\TMP

But, if you add the same lines to CONFIG.SYS: 

SET TEMP=C:\TMP 
SET TMP=%TEMP%

you get: 

TEMP=C:\TMP
TMP=%TEMP%

but not TMP=C:\TMP. The enviroment variable TMP now has the value composed by the letters "%", "T", "E", "M", "P", "%". For that reason, in CONFIG.SYS, you must write the values explicitly as follows: 

SET TEMP=C:\TMP
SET TMP=C:\TMP

This is because variables are not expanded during CONFIG.SYS processing, but they are when run from a shell (command line).

This variable change the user interface program to load at boot, and replace it with Atshell program. 

SET RUNWORKPLACE=x:\path\ATSHELL.EXE

This causes the desktop shell to be launched immediately when ATSHELL first starts up, without displaying the ATSHELL dialog. (The ATSHELL dialog will appear, however, when/if you close the desktop shell program.)

This enables a simple 'secure' mode. When ATSHELL is started with this parameter, the command prompt and configuration options are disabled and inaccessible. USE THIS OPTION WITH CAUTION -- if you don't have an alternative method of booting (such as boot diskettes or a maintenance partition), you won't have any way of changing the configuration (or even removing ATSHELL from CONFIG.SYS), unless the desktop (or startup) program itself gives you access to a command prompt. Alternatively, you can use this in conjunction with the multi-user local logon feature of Security/2, by setting 'atshell /s' as the local shell for non-privileged users, and keeping the WPS (or something else) for the system administrator.

TIMESYNC

New with eCS 1.1 

SET TIMESYNC=<parameter>

ex: SET TIMESYNC=0

TMP

Here you can define a directory were OS/2 and programs can store temporarily files. It is a god idea to use the same directory as used in SET Temp. Check the directory time by time to see if there are temporally file that you can delete, because some applications forget to delete their temporally files.

USE_HOSTS_FIRST

If USE_HOSTS_FIRST is set up, TCP/IP will first look in the local file ..\Etc\Hosts for the dotted IP address for a specific Hostname on the internet.

Let me explain - Whenever you connect to the internet and you access a host (for example http://www.netlabs.org), your browser must know the dotted IP address (for example 195.65.67.48) for the host. So the browser contact a Domain name Server (DNS) and ask for the IP address. This takes some time, to speed up internet connection you can define in the Hosts file the hostnames and the IP addresses.

OS/2 will only use Hosts file if USE_HOSTS_FIRST is set to 1. You can define all kind of hosts www-server, mail-server, news-server, ftp-server or whatever else. To get the IP address for a host type "host" and the hostname in an OS/2 window. The actual Path for the host file is defined by the ETC environment variable. 

SET USE_HOSTS_FIRST=1

Value can be any full path. Relative paths are not allowed.

USER
