Semantic-enabled Resource Discovery, Composition and Substitution in 802.11 Pervasive Environments

A system and method for computer control of machine processes, including a dynamic menu feature used in the selection of processes and the definition and selection of operating parameters used by a process control program to direct the performance of the process by the machine. Data structures for a multiplicity of processes are defined and stored. Values stored in the data structures indicate which processes are available for use and the process control program associated with each process. Furthermore, for each parameter of each process a data structure contains an indicia of whether the parameter is a forced entry parameter (which must be given a value before the process is run), a may change parameter (with a default value that may be changed when the process is run), or a locked parameter which has a fixed value. An engineering set up program enables interactive computer controlled performance of the steps of storing the above-mentioned data structures, entry of values into the data structures, and the entry of default parameter values. An operator control program, utilizing the stored data structures, enables interactive computer controlled performance of the steps of selecting one of the enabled processes, entry of parameter values, and running of the selected process.
