The PUT, GET, MOVE, and DELETE CONTAINER commands used to build and interact with a channel are similar to those used in CICS® business transaction services (BTS) applications. (For information about BTS, see the CICS Business Transaction Services manual.) Thus, programmers with experience of BTS will find it easy to use containers in non-BTS applications. Furthermore, server programs that use containers can be called from both channel and BTS applications. An example of this is shown in Figure 1.
