Use

Application.displayalerts = false

to suppress alerts. Be sure to set back to true as it will remain false
after the macro quits. Then alerts like closing a file without saving will
not appear.

I am writing a macro to merge adjacent cells that have the
same values in the header row. But every merge prompts
the following message:

The selection contains multiple data values. Merging into
one cell will keep the upper-left most data only.

The choice is OK or Cancel.

What is the command to suppress this message and take OK
as default? Thanks.
