Table 1 provides the following
information regarding APPCCMD macroinstructions and the flow of information
from the application to VTAM:
- Transfers normal data from the application to VTAM
- Flushes (empties) SEND buffer (normal data) into the network
- Possibly causes information to be sent into the network
- Transfers expedited data from the application to VTAM
- Causes a SEND indication to be sent to the partner
- Causes a DEALLOC indication to be sent to the partner
- Causes a CONFIRM indication to be sent to the partner
- Causes a CONFIRMD indication to be sent to the partner
- Causes an ERROR indication to be sent to the partner
