Attention identifier constants, DFHAID

The standard attention identifier list, DFHAID, simplifies testing the contents of the EIBAID field. Table 1 shows the symbolic name for the attention identifier (AID) and the corresponding 3270 function.

You can get a copy of the list by copying DFHAID into your application program. For COBOL users, it consists of a set of 01 statements that must be copied into the working-storage section. For C users, it consists of a series of defined constants. For PL/I users, it consists of DECLARE statements defining elementary character variables.
