IDL is mainly for analysing data. However, we have used it in the past for
doing some simple controlling of laboratory equipment. The most complex task
we've done in that language consisted of
1. Reading from a CCD camera
2. Controlling X,Y,Z stepper motors that the camera was mounted on
3. Reading from a amp meter
4. Reading from a programmable counter
All the instruments used a GPIB interface. We used CALL_EXTERNAL on a Sun
Sparcstation to connect to C libraries to communicate with the GPIB controller.
It worked pretty well, although we would hand off control to a OS/2-based PC
for more sophisticated handling of the CCD camera.
