Remarks
This method returns a special, compressed string representing the screen contents found in a rectangle bounded inclusively by the leftRow, leftColumn and rightRow, rightColumn coordinates.
The encoding of the string utilizes run-length-encoding to compress duplicate characters. It is intended for use in the Inventu Viewer+ Terminal Emulation web framework and is not intended for general use.
The Inventu Viewer+.SCWebControls.SCPassThru custom control encapsulates the use of this method and ties it together with the DHTML framework function SCdecode().
