Program link server adapter data-containers
The program link server adapter, DFHMASDP, stores its state, processing status, inputs, and outputs in BTS data-containers.
The program link server adapter uses the EXEC CICS LINK command, and passes either a COMMAREA that can be up to 32 767 bytes in length to the target application, or a channel and containers.
The following table lists the standard set of DFHMASDP data-containers. Additional data-containers might be made available to DFHMASDP for its processing, if the program link is passing a channel and containers.
| Name | Size (bytes) | Contents and usage |
|---|---|---|
| DPL.DATA | 40 006 | Contains the programming link to the target application. If the link is using a channel and containers, this data-container also stores the channel name and the number and name of the containers that must be passed in the channel. |
| COMMAND.INPUT | Variable with a maximum of 32 760 | Input data from the flow navigator. |
| COMMAND.OUTPUT | Variable with a maximum of 32 760 | Output from DFHMASDP. |
| COMMAND.STATUS | 256 | Status information for DFHMASDP, including:
