To read data from a connected TCP/IP socket, you invoke the READ( ) method on the corresponding socket object (SELF:READ( ) within the corresponding READ-RESPONSE event procedure or method). You can invoke this method on a connected socket at any time to read data. However, the method blocks depending on the amount of data available on the socket, the reading mode that you use, and the timeout value (set by the SO-RCVTIMEO option of the SET-SOCKET-OPTION() method).

This is the syntax of the READ( ) method:

READ(
      memptr-expression 
    , position 
    , bytes-to-read
      [ , mode ]
    )
