DDE Array Points
CX-Supervisor supports arrays in DDE, for both 'Client' and 'Server' transactions. DDE Client data
transfers are initiated by CX-Supervisor, either sending or requesting data from external DDE
Applications (such as Microsoft Excel). DDE Server data transfers are initiated by external DDE
Applications either sending or requesting data to or from CX-Supervisor.
Refer to the CX-Supervisor Script Language Reference Manual for further details.
DDE Client Array Points
This chapter explains how to create DDE Client Array points. This is similar to the way normal DDE
Client points are created, except extra information is required to specify the range of the array and
also whether it is to be stored as a row or column in the Server application.
1, 2, 3...
In the CX-Supervisor Runtime environment, the above DDE Client array transactions are initiated by
means of script in the same way as single DDE Client points. The CX-Supervisor script below gives
examples of the facilities available with DDE Client array points:

The following are valid array item names: "R1C1:R3C1[col]",
"first:last[c]", "R5C2:R5C5", "r1c1:r3c1[column]".
