Command language, graphical user interface and delivery

LISREL is mainly syntax-based, although recent versions have featured a graphical user interface

Graphical user interface

In computing, a graphical user interface is a type of user interface that allows users to interact with electronic devices with images rather than text commands. GUIs can be used in computers, hand-held devices such as MP3 players, portable media players or gaming devices, household appliances and...

SSI (Scientific Software International) has recently changed from e-Academy to a "home-built" solution for distributing the rental (6-month or 12-month) versions of their software.
