VPE software
The VPE software is a programmer shell that is written in M and runs on a range of M implementations. While its greatest power is realized in a Vista/DHCP VA environment, it is still incredibly handy and well behaved in a pure M world -- and it is free!
The latest version of this program is found at the Hardhats site at http://www.hardhats.org/tools/vpe/vpe_db.html.
