Instant turnaround revisited: our wit goes BATty

In earlier reports (Kreider, et. al., 1970; Williams, et. al., 1970; Sim, et. al., 1971a, Sim, et. al., 1971b) we have described and discussed the general character and some social science applications of a system of instructional computing developed at the Pennsylvania State University. The service is one of "Speed Batch" processing (Bernitt, 1971) which gives immediate response to "small" jobs. It was originally based on the WATFOR dialect and processor, so we have used the acronym WIT (for Watfor Instant Turnaround) to refer to the system. In this report we note progress in the further development of the service. In a later report we will discuss applications in social science instruction.
