The following figures show the flow of control in some of the most typical kinds of conversations. These examples use the MVS TP conversation calls; for similar flows using CPI Communications, see Figure 3 and CPI-C Reference.

In these flows, the first occurrence of each callable service (ATBxxxx) is accompanied by the corresponding conversation service name, for example, the Allocate service. The callable services are abbreviated to show only the pertinent parameters. For clarity, the parameter values appear in parentheses after the parameter name; in actual syntax, the values are positional.
