I often have the need, but I do the same as you:
cobble something together. I think it would be
almost impossible to write a "generalized"
preferences system, although I'm sure if you
gave it a try you would be using an object of
some sort. :-)
Objects are a terrific way to keep track of the
current "state" of something. They are used, for
example, in FSC_PSConfig to keep track to the
current state of the PostScript device and in MPI_Plot
to keep track of current line plot settings.
Cheers,
David
