This section explains the syntax of the API functions which implement the XATMI interface. The text in this section is quoted from 7. COBOL Language Reference Manual Pages which is the syntax reference section of the X/Open CAE Specification Distributed TP: The XATMI Specification published by X/Open Company Limited.

Additional notes on using these functions from OpenTP1 UAPs are enclosed in << >> symbols.

The XATMI interface has the following API functions. The function TPINTRO defines data areas invoked from API functions using the COPY statement.

• TPINTRO - COPY files for the XATMI interface
• TPACALL - Send a service request.
• TPADVERTISE - Advertise a service name.
• TPCALL - Send a service request and synchronously await its reply.
• TPCANCEL - Cancel a communication handle for an outstanding reply.
• TPCONNECT - Establish a conversational service connection.
• TPDISCON - Terminate a conversational service connection abortively.
• TPGETRPLY - Get a reply from a previous service request.
• TPRECV - Receive a message in a conversational connection.
• TPRETURN - Return from a service routine.
• TPSEND - Send a message in a conversational connection.
• TPSVCSTART - Start a service routine.
• TPUNADVERTISE - Unadvertise a service name.

XATMI-interfaced API functions whose names begin with TP can be used only with the TP1/Server Base. They cannot be used with the TP1/LiNK.
