Well, if you know what the line is going to contain, that can be
written as

  a, b, c = f.readline().split()

However, that does give you byte-strings since that's what comes out
of files.  If you know they're ints, you can force that:

  a, b, c = map(int, f.readline().split())

In both Fortran & BASIC, you specify that information somewhere as
well.  However, it sounds like you define those at the
variable-definition level (it's been over a decade since I done any
BASIC and far longer since I've even touched any Fortran, so forgive
me if I'm a tad rusty) instead of where its read from the file.
