CclScreen class

The CclScreen EPI class maintains all data on the 3270 virtual screen and provides access to this data. It contains a collection of CclField objects which represent the fields on the current 3270 screen.

A single CclScreen object is created by the CclTerminal object; use the screen method on the CclTerminal object to obtain it. The CclScreen object is updated by the CclTerminal object when 3270 data is received from CICS®. A dataStream exception is raised if an unsupported data stream is received.
