find user names

Is there a way to find out ALL the user's account names on my computer - maybe with getenv ? Thanks.

Is there no way to do this with blitz commands?

if you find the C++ command you need on msdn, and ask really nicely, then someone on here might write a userlib for you to add the command into you're blitzplus command set.
