CONFIG.SYS - SET Statements

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).

WarpCenter

SCCANBENUKED

Allows the Warpcenter to have a delete option on its context menu.

SET SCCANBENUKED=value

or

SET CANBENUKED=value

Parameters:

Value can be ON or 1 or OFF or 0 . If this parameter is not set it defaults to OFF

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

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x
No	No	Yes	Yes

SCFINDUTILITY

With this entry you can use a different search program in the Warpcenter. By default, the Warpcenter starts a very slow program when you press this button Warpcenter Find Button In the \OS2\APPS directory is the fast find utility PMSeek.exe which you can use instead of the default program.

SET SCFINDUTILITY=<value>

or

SET FINDUTILITY=<value>

Parameters:

Value can be any program with a full path or object-id. If this parameter is not set the default find utility is used.

Example:

SET SCFINDUTILITY=Programe_Name.exe

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x
No	No	Yes	Yes

SCKILLCONFIRMDISABLED

Avoid the "Are you sure ..." dialog if using the Warpcenter kill feature. :Note. You must also have the SET SCKILLFEATUREENABLED variable installed.

  SET SCKILLCONFIRMDISABLED=value

or

  SET KILLCONFIRMDISABLED=value

Parameters:

Value can be ON or 1 or OFF or 0 . If this parameter is not set it defaults to OFF

Example:

  SET SCKILLCONFIRMDISABLED=ON

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x
No	No	Yes	Yes

SCKILLFEATUREENABLED

This entry enables you to use the Warpcenter window list Warpcenter Window List as an application killer. To kill an application you must hold down the key and click the left mouse button on the window list icon on the Warpcenter. A drop down menu appears and you can then select the process you want to kill. If you have selected a process, the system will ask you if you really want to kill the process.

SET SCKILLFEATUREENABLED=value

or

SET KILLFEATUREENABLED=value

Parameters:

Value can be ON , 1 , OFF or 0. If this parameter is not set it defaults to OFF

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

Example

SET SCKILLFEATUREENABLED=ON

or

SET KILLFEATUREENABLED=ON

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x
No	No	Yes	Yes

SCUSEPRETTYCLOCK

With this entry you can change the look of the Warpcenter clock to this: Warpcenter Clock. It replaces the normal Warpcenter clock with one that has a digital display.

SET SCUSEPRETTYCLOCK=<value>

or

SET USEPRETTYCLOCK=<value>

Example

SET SCUSEPRETTYCLOCK=ON

Parameters

Value can be ON or 1 or OFF or 0. If this parameter is not set the default clock is used.

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

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x
No	No	Yes	Yes

SHAPIEXCEPTIONHANDLER

SHELLEXCEPTIONHANDLER=OFF

Disable the WPS exception handler.

SET SHELLEXCEPTIONHANDLER=OFF

Note: This directive seems to be an environment variable in WARP 3 with Fixpack #36 and WARP 4 with Fixpack #5. This means that you have to use the format "SET SHELLEXCEPTIONHANDLER=OFF ". On older releases it had to be only "SHELLEXCEPTIONHANDLER=OFF"

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x
	*	*	Yes

ShellHandlesINC

Increases the number of file handles.

SET ShellHandlesINC=Value

Parameter:

Value is the number of handles by which the standard number of handles per shell process are increased. With a standard of 30 handles and SET ShellHandlesINC=20, 50 file handles (30 + 20) are available to each shell process.

Value can be any integer between 0 and approximately 255, but highly dependent upon available memory.

This setting is only available beginning with Warp 4 Fixpack #6.

Platform Support:

OS/2 2.x	OS/2 3.0	OS/2 4.0	OS/2 4.5x
		FP6+	Yes
