  The type "unsigned long long" is 64 bits for twenty digits per 
the following link; plus others described:
http://en.wikipedia.org/wiki/Integer_(computer_science)#Common_integral_data_types

  The 20u00 declaration establishing the RPG 8-byte unsigned 
integer data type would be an equivalent to the unsigned long long 
type declaration.
