Yes, the name is 'SetEnvironmentVariable()'. The only problem is that it's only valid for the current process (and processes that are created by the current one). If you want them to persist, you'll have to add them to the user's environment (different for NT & Win9x)

in particular, i will need to set CLASSPATH.
i wanted to set it when installing my software.
so it would seem that i would want them to persist.
this would be in windows NT.

do you know how this is accomplished?

Yes (NT is easier than 9x ;-). Simply add a value to 'HKEY_CURRENT_USER\Environment' supplying the variable's name as the value name. If you want to set the value for all users, you should add this value to 'HKEY_USERS\<some SID to be replaced>\Environment'
