Unless you said USAGE IS COMPUTATIONAL, which left the compiler
free to pick a more efficient storage format internally.
BTW, one thing I think COBOL did right was not limiting you
to some arbitrary compiler or language defined maximum size
for numbers. You could declare something as PIC 9(100) and
do arithmetic on 100-digit numbers if you wanted. (At least
potentially -- not sure if all compilers would really
support something that big.)
