There are differences between $mydata and @mydata.

The $mydata scalar is a reference to an array-of-arrays data structure. There are 3 arrays, each with 3 elements.

@mydata is a flat array consisting of 9 elements.

It seems like whatever OLE module you're using requires you to use the reference to an array-of-arrays, not a flat array. Refer to the module documentation. Can you tell us the exact module you are using?

A good reference is perldsc.
