IBM's APL2/PC includes the AP488IBM and AP488NI auxiliary processors for the IEEE-488 General Purpose Interface Bus (GPIB) to control a wide variety of I/O devices, instruments and tools. Process control and measurement in the lab and on the production line through the GPIB can be efficiently implemented with APL2/PC.The manuals for the GPIB software are large, and the manuals for the instruments that connect to the bus can be even larger. The system does have many capabilities, but most situations can be handled with a few basic commands. This short introduction can't claim to provide all that's needed to use the GPIB, but it may be enough to start an application, and it purports to point out the pertinent parts of the paper pile.
