Attention identifier (EIBAID)

For every terminal control (or BMS) input operation that is associated with a display device, an attention identifier (AID) is placed in the EIBAID field of the EIB. The AID indicates which method the terminal operator has used to initiate the transfer of information from the device to CICS®; for example, the ENTER key, a program function key, and so on. The field contents remain unchanged until updated by a new input operation.

EIBAID can be tested after each terminal control (or BMS) input operation to determine further processing, and a standard attention identifier list (DFHAID) is provided for this purpose.

Alternatively, for COBOL programs only, the HANDLE AID command can be used to pass control to specified labels when the attention identifiers are received.

EIBAID is also updated at task initiation for non-ATI tasks.
