specifies whether the function call is performed as array function
call.
If set to true, the result of the function call will be
calculated similar to array formulas in a spreadsheet document. The
return value of the function call will usually be a sequence of
sequences containing the values of the resulting array. Example: If the
function ABS is called for a 3x2 cell range, the result will be a 3x2
array containing the absolute values of the numbers contained in the
specified cell range.
If set to false, the result of the function call will be
calculated similar to simple cell formulas in a spreadsheet document.
The return value of the function call will usually be a single value.
Of course, some functions always return an array, for example the
MUNIT function.
For compatibility with older versions, the default value of this
property is true.
