Terminal Control

Your application program communicates with the terminal via the CICS terminal control program (TCP) using information defined in the terminal control table (TCT). Terminal control implies use of unformatted screens, as described in Tutorial: Creating a Simple Transaction. The following commands are commonly used:

• HANDLE AID

• ISSUE COPY

• ISSUE PRINT

• RECEIVE

• SEND

Of these commands, only HANDLE AID has SAS/C product dependencies. HANDLE AID is implemented by specifying a function name for the error handler, rather than specifying a label, as in this example:

EXEC CICS HANDLE AID option(function-name) ... ;

See Handle Condition and Handle AID for more information on this command.
