CONFIG.SYS - SET Statements

From EDM2

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.
  • SCFINDUTILITY - Use a different search program in the Warpcenter.
  • SCKILLCONFIRMDISABLED - Avoid the "Are you sure ..." dialog if using the Warpcenter kill feature.
  • SCKILLFEATUREENABLED - Enables Warpcenter window list Warpcenter Window List as an application killer.

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

SMADDSTAR

SET SMADDSTAR=1

SMCLASSES

SET SMCLASSES=Wptypes.idl

SMEMIT

SET SMEMIT=H;IH;C

SMINCLUDE

Defines the directories where the special SOM header files are stored. 

SET SMINCLUDE=Paths
Parameters
Paths can be any full path or any relative path. If you use more than one path, the paths must be delimited by a semicolon.

SMNOTC

SET SMNOTC=1

SMTMP

Points to a directory used to store temporary files. 

SET SMTMP=<path>
Parameters
Path can be any full path.

SMG_Path

This is used by the IBM AO-Manager. 

SET SMG_Path=Path

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

SMG_Pl2Nlg

This is used by the IBM AO-Manager.

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