Dear Nick,

   Fortran dates from the days of "unit record" equipment, fixed length
records on magnetic tape, and variable length records on paper tape.
Part of the Fortran language spec is an I/O system for those days
that pads incoming character data on read an arbitrary number of
blanks on every "formatted" read, and which provides _no_ way to
detect the original line termination.

   The language is also remarkably clumsy in handling variable length
strings, preferring to pad, again with blanks, on every string assignment.

   It make fore great fun in programming for it.

   I would advise you to stick to C/C++/java, etc.

   Regards,
     Herbert
