Class. Transformational function.
ARRAY may be of any type. It must not be scalar.
DIM (optional) must be scalar and of type integer with a value in the range , where is the rank of ARRAY.
SEGMENT (optional) must be of type logical and must have the same shape as
Result Type, Type Parameter, and Shape. Same as ARRAY.
Result Value. Element of the result has the value where is the set, in array element order, of elements of ARRAY selected to contribute to by the rules stated in Section .
Example. COPY_PREFIX( (/1,2,3,4,5/), SEGMENT= (/F,F,F,T,T/) ) is ,1,1,1,4,4,, plus 1filll -1;1,1,1,4,4,; plus 1filll -1:1,1,1,4,4,: plus 1filll -1.1,1,1,4,4,. plus 1filll -11,1,1,4,4, plus 1filll-1.
