Format Date and Time from a FORTRAN Program
The user is asked to enter a language. All date and time formatting and
conversion is done by using the language entered by the user. The time
and date used in the examples is the current system time obtained by
calling the HP 3000 system intrinsics CALENDAR and CLOCK.
