Tavora, Carlos J.2022-12-202022-12-2019784843940https://hdl.handle.net/10657/13080This thesis describes a set of programs designed to extend the capability of the BASIC language to allow periodic acquisition of signals and control of devices. These programs allow a system user to define sets of inputs and sets of outputs from a group of signal lines. Output data are converted into the data formats of external devices and input data are converted into a data format compatible with programs written in BASIC. The extensions to BASIC described in this thesis provide a casual programmer with the means to perform data acquisition and control with minimum knowledge of system software. An application of the software described in this thesis to a system that will test student's proficiency in the use of laboratory equipment is presented and evaluated.application/pdfenThis item is protected by copyright but is made available here under a claim of fair use (17 U.S.C.
