This command writes the data from the preliminary declared Double Type Array to a specified element of an IDN to a specified drive. The number of elements to write is limited by <size> parameter. This function works only for IDNs containing more than one Double Type value in array method .
<element> is optional. In general, only element 7 is used (default).
