Comparison with Waiting in Releases Prior to 2.1

GRAPH_RECEIVE offers a simpler waiting method than was possible with prior releases:

Waiting with GRAPH_RECEIVE (rather than one of the graphics-program-related function modules) is cleaner. GRAPH_RECEIVE reports all messages received in the same way, regardless of which graphics program sent it. As a result, the ABAP program can handle them all consistently.

For calling any graphics function module, the STAT parameter now only has two meaningful values:

'2': open new window and send data
5': send data to an open window

The RWNID and M_TYP parameters are no longer necessary when calling any graphics function modules except GRAPH_RECEIVE. (Also, for GRAPH_RECEIVE, M_TYP has been re-named MCODE.)

Older ABAP programs that use previous waiting mechanisms will still run correctly. However, for new program development, use GRAPH_RECEIVE. Do not mix the old and the new waiting mechanisms in a single program.
