Setting environment variables on Windows

On Windows™ platforms, environment variables can be set by one of the following methods:

• In a command window, with the SET command.
• In the registry, for the current user in HKEY_CURRENT_USER or a global setting in HKEY_LOCAL_MACHINE.

For more details, refer to the documentation of your Windows system.

On Windows, double quotes do not have the same meaning as on UNIX™ systems. For example, if you set a variable with the command SET VAR="abc", the value of the variable will be "abc" (with double quotes), and not abc.

When using Informix®, some variables related to the database engine must be set using the SETNET32 utility.
