Write value from a cell (getting via DDE link) to another cells.
 

I've got a DDE link between Excel and another software. The value of the
registers in that software is not static (ie.. change time to time). It is
displayed in a cell of Excel, using the syntax
[=software|subject!variable_name]. I want this value to be written to
increasing cells periodically (eg. each minute). How can I do this task?
Could someone help me to solve this problem?
