There are three pacing stages for application program-to-application program with VR from an intermediate host to the SLU host connection. All three pacing stages use adaptive pacing. Figure 1 shows the pacing stages for this example. Stage x and stage y use adaptive pacing and stage z uses either adaptive or fixed pacing. Figure 1 shows the pacing stages for this example. See Table 1 and Table 2 for examples of the values used by VTAM® to set the pacing window values. Figure 1 shows the pacing stages for this example.

Table 1 shows sample definition statement coding and corresponding windows when data flows from the PLU to the SLU. Table 2 shows sample definition statement coding and corresponding windows when data flows from the SLU to the PLU.
