It might take 30 seconds to write a wrapper that could do this.
Cheers,

Thanks Mike,
I suspect that's what I'll have to wind up doing. The code kicks out about 100 printf outputs, all different depending on the inputs, and sometimes I'll need things to just print to a file or screen, but sometimes it would be nice to have a character string kicked out for a title, say...

STRING and PRINT/PRINTF take arguments and format strings in the same
manner, so it's not hard to change between them, i.e.,
printf, lun, a, b, c, format=format_string
or
s = string(a, b, c, format=format_string)
