The move to WIMPS interfaces has delivered excellent models and interfaces for simple operations on
personal computers. Unfortunately, this has not been matched by the development of models and interfaces
for the operations required in more complex systems, traditionally provided by applications such as the "csh",
and more recently AppleScript. In this paper we introduce and demonstrate the use of the Prograph system,
together with a sample of suitable utilities, as the appropriate tool for shell-type operations in a WIMPS
environment.
