Correct, although you may want (define myf10-5-fmt (fmt "F10.5")) and use myf10-5-fmt such as to avoid repeated parsing of the string "F10.5". I have also thought of parsing the format strings during compile time, but that would force me to simplify fmt to a syntax considerably more constrained than the current procedure. Thanks for your attention, Jos

Jos, Ryan, Thanks for your suggestions. They both work -- for planet-fmt the code is ((fmt "F10.5") 12.345678). I think I will take srfi/48, as it does not require connecting to PLaneT.
