Abstract
In this paper we present the extensive use of a scripting language
(Tcl) to run human readable/editable scripts in a CORBA distributed
batch environment. The developed system is the "Advanced Process
Control Framework" as outlined in the "APC Framework Initiative" which
is a research and development project undertaken by AMD and Honeywell
under the support of the U.S. Department of Commerce, National
Institute of Standards and Technology. The APC Framework System has
been deployed in AMD's fab 25 and is fully functional. The paper
discusses the issues involved in developing scripting mechanism which
is capable of both interacting with other CORBA components and
handling various data structures which are otherwise not addressable
by the underlying scripting language. The flexibility and
extendibility of the Tcl scripting language makes it easy to extend
the core language. The paper also establishes the need for
thread-safeness of Tcl. Examples of various data manipulation
operations, calls to different CORBA components, and calls that help
in synchronization are discussed.
