Hi Gary,

It's interesting info. Thank you.

>A fellow I worked with a few years ago wrote a C++ COM object to test what was sent to it when we were fruitlessly trying to pass safearray's to COM servers from VFP6. Starting with VFP8, the following code works:
>
>COMServer = CreateObject('something.class')
>DIMENSION MyArray as BYTE
>MyArray = 1 && Works without this line too
>COMARRAY(COMServer,10) && Pass by ref
>COMServer.Method(@MyArray)
>
>The test object shows VT_ARRAY of VT_UI1 VT_BYREF
>
>If I leave off the "as BYTE", I get VT_ARRAY of VT_VARIANT VT_BYREF
>
>If I use:
>DIMENSION MyArray as STRING
>MyArray = 'A'
>I get VT_ARRAY of VT_BSTR VT_BYREF
>
>The "as" clause seems to make a difference.
