Specify an array variable reference in the following format:

VARIABLE_NAME[N1,...Nn] WIDTH [, PREC] 

VARIABLE_NAME[N1,...Nn] is an array variable reference. The array must be a string, integer, or float array, and the reference must be specific (that is, to a single element in the array). The array can be multidimensional. Subscripts can be either positive integer constants or integer variables. (See Example 1.)
