The line PUBLIC DIMENSION aRptQty( 3, 4 ) creates public variable DIMENSION and public array aRptQty( 3, 4 ) in VFP 6. It should generate an error in VFP 7 because DIMENSION isn't a legitimatee clause of the PUBLIC command. You can change it to

PUBLIC aRptQty( 3, 4 )
* or 
PUBLIC ARRAY aRptQty( 3, 4 )
