===Dope vectors===
{{Main|Dope vector}}
The addressing formula is completely defined by the dimension ''d'', the base address ''B'', and the increments ''c''<sub>1</sub>, ''c''<sub>2</sub>, ..., ''c''<sub>''k''</sub>. It is often useful to pack these parameters into a record called the array's ''descriptor'' or ''stride vector'' or ''[[dope vector]]''.<ref name="andres" /><ref name="garcia" /> The size of each element, and the minimum and maximum values allowed for each index may also be included in the dope vector. The dope vector is a complete [[handle (computing)|handle]] for the array, and is a convenient way to pass arrays as arguments to [[subroutine|procedures]]. Many useful [[array slicing]] operations (such as selecting a sub-array, swapping indices, or reversing the direction of the indices) can be performed very efficiently by manipulating the dope vector.<ref name="andres" />▼
