    The fact that the format string was up front was way done on the list of
advantages of PRINT USING (so far that many would consider it a
disadvantage, or at least were neutral about it).

    The primary advantage of the Basic PRINT USING was that it offered
formatting options that were difficult any other way.  For example:

    f = 1.0
    print using "###.##"; f        ' prints "  1.00"   (exactly six
characters)

otherwise you'd have to write:
    f = 1.0
    S$ = str(f)
    i = instr(S$, ".")
    if i = 0 then S$ = S$ + ".00"
    else S$ = Left$(S$+"00", i + 2)
    S$ = right$("     " + S$, 6)
    print  S$

Personally, I think the latter. It is interesting to note that the PRINT
statement in BASIC had cout-style printing from the start; the printouts
were
concatenated using ";" or "," operators, if one can call them operators.
However, for the sake of readability and ease-of-use, many dialects later
added the PRINT USING statement that allowed to you to provide a (type
independent, i.e. no loss of type safety) format string first, and then let
the arguments to the string follow.
