Thanks Liam and Riemar,
Right now, I don't expect the user to run from the command line since
the GUI is available (and, for the user, less intimidating.)
Since the data format doesn't change (it's always an image) I have an
advantage over more generic data handling. I think that I could add a
RecordMacro method into the event handling to provide. I would have
to have a RECORD property/flag that tells the handler when to record
the step and when not to. The behavior I hope to see is similar to that
of ImageJ (http://rsb.info.nih.gov/ij/) . When recording, a simple text
editor appears listing the steps taken. Here's an example from ImageJ...
> run("Threshold...");

> run("Add...", "value=25");
> run("Measure");
In the IDL case, each set corresponds to a method which could be called
in order by CALL_METHOD. The trick, I think, might be the arguments,
such as the ADD, value = 25. Perhaps the macro should include the
object class, the method and any arguments... I don't know what to do
with keywords.
ClassName Method P1 P2 P3 P4 PN
HBB_HISTOGRAM SETTHRESHOLD 48 170
HBB_IMAGE ADD 25
I'll have to think about that.
Thanks again,
Ben
