ASCAN question

I have an array (aWork ) , and each element is an array with 4 elements: The data arrays are: [1] is a character field of 5 digits [2] is a counter [3] is an accumulator ( totals ) [4] is a description I want to use aScan on aWork on the first element, and when I find the matching array, I will increment [2] and [3]. I can I use ASCAN( ) to search an element in an array of arrays ?
