Tcl is an easily-embeddable scripting language created by John Ousterhout. Its ZOOM binding is very briefly described at gondolin.hist.liv.ac.uk/~cheshire/zoom/tcl.html
To give a flavour of the Tcl binding, here is ZOOM's equivalent of the ``Hello World'' program: a tiny Z39.50 client that fetches and displays the MARC record for Farlow & Brett Surman's The Complete Dinosaur from the Library of Congress.
