CONFIG.SYS - SET Statements
|The Config.sys Documentation Project|
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:
Note that SET commands in CONFIG.SYS behave differently than when entered on the command line.
So, when you issue the following commands in a OS/2 session:
SET TEMP=C:\TMP SET TMP=%TEMP%
But, if you add the same lines to CONFIG.SYS:
SET TEMP=C:\TMP SET TMP=%TEMP%
but not TMP=C:\TMP. The environment 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).
