The Remote Build client is represented as a gray box to the left of a large, rectangular box representing the MVS™ system. Inside the MVS box, there are four smaller boxes aligned vertically on the left. The boxes are labeled RCCINIT, RCCBLDS, RCCMVS (BCL) and RCCBLDW (Child process). A one-way arrow passes between the four boxes. A two-way arrow between the RCCINIT box and the box in the upper right portion of the MVS box labeled RACF® represents User ID validation. There is a two-way arrow labeled TCP/IP session between the RCCBLDS and RCCBLDW boxes. The interface between the Remote Build client box and the RCCBLDS box is labeled TCP/IP connection. In the bottom right portion of the MVS box, there is a circle labeled Script processing, and there is a two-way arrow between the RCCBLDW box and the Script processing circle. End Figure 1.
