Syntax

DIM<n>(array-name)

DIM(array-name,bound-n)

n: specifies the dimension, in a multidimensional array, for which you want to know the number of elements. If no n value is specified, the DIM function returns the number of elements in the first dimension of the array.
array-name: specifies the name of an array that was previously defined in the same DATA step.
bound-n: specifies the dimension, in a multidimensional array, for which you want to know the number of elements. Use bound-n only when n is not specified.

Note: This distinction is important when the lower bound of an array dimension has a value other than 1 and the upper bound has a value other than the total number of elements in the array dimension. [cautend]
