The following section will establish the length of the string abc in characters (5), the number of entries in the array int_array (100 regardless of the number that have been assigned values), and the number of entries assigned in the parameter DBIC (3).

 local string abc, int int_array[100]

 abc = "Hello"
 print f$len(abc)

 int_array[1] = 100
 int_array[2] = 200
 print f$len(int_array)

 dbic = 1,2,3
 print f$len(dbic)
