ACOPY() bug

It has to be either a bug in FoxPro or an error in the documentation, right?

Documentation says "If the destination array already exists, it is
redimensioned to the size of the source array."


DIMENSION arrayX(4, 5)
DIMENSION arrayY(1, 5)
ACOPY(arrayX, arrayY) && gets "Subscript is outside defined range"
error

From the VFP9 help under Remarks for ACOPY():
Copying a member array to an existing non-member array with certain
dimensions using the ACOPY( ) function might generate the error, "Subscript
is outside defined range." You can avoid this error changing the dimension
of the destination array to a single element before calling ACOPY( ). For
more information, see DIMENSION Command.

So it's a bug. At least there's a workaround - dimension the array before
copying.

Anyway, neither of these arrays is a member of anything.

Nah, once it's documented, it becomes a *feature*. ;)
