Jacob says (of outputting numbers with leading zeroes)

<<I do not think there is a routine to do it in the standard libraries, but it
is not hard to implement with a few calls to routines in the standard
libraries.>>


No, that's wrong, there are extensive formatting capabilities defined in
Ada 95 that share the concept of COBOL picture strings. This is a particularly
trivial case (you just use a picture of all 9's). Have a look at the package
Ada.Text_IO.Editing in annex G. This capability is fully implemented in all
current versions of GNAT.
