Return the length of the argument.
val = len(item)
len will return the length of the argument item. If it is a Minc list, it returns the number of elements in the list. If it is a string, it returns the number of characters in the string. For other types it returns “1”. (Note: this includes pfield-handles and table-handles — see the tablelen scorefile command for accessing table lengths).
After parsing he following scorefile segment:
arr = { 1, 2, 3 }
val1 = len(arr)
val2 = len("hey there")
val1 will be set to 3, and val2 will be set to 9.
