Data detection using the procedural model
To detect data procedurally, you can simply read whatever data is available on the socket object using the READ( ) method. Using this model, you do not use the READ-RESPONSE event, and ABL does not automatically notify your application when data is available to read on the socket. You can also check:
*To see if the socket is connected using the CONNECTED( ) method
*To see how many bytes are available to read, using the GET-BYTES-AVAILABLE( ) method
How you use these methods depends on your application requirements and the options that you choose on the READ( ) method. For more information on READ( ) method options, see Reading data on a socket.
