There is nothing like a "private" method in IDL.
However, there are some things you can do to keep
neighborhood eyes from oggling the babes in the
backyard pool.

For example, you can give your "private" methods
ugly names (I usually append an underscore to the
method name), and you can set the HIDDEN compile
option, so the casual user doesn't know it is there
when the object code is compiled:

PRO myobject::_myprivateMethod
compile_opt HIDDEN
...
END

But nothing is going to stop a determined 14-year-old
with a good set of field glasses. :-(

Cheers,

David
