    I'm not sure what you did incorrectly, because the first form is entirely correct and valid for as long as I can remember in SKILL. I just cut and paste it, and it worked fine. For example:

    variable='("hello" 4.2 27)
    out=stdout
    foreach(val variable
      fprintf(out if(numberp(val) "%N\t" "%s\t") val)
    )

    this worked perfectly. The "%N" (as covered in the documentation for fprintf/printf) is for displaying any kind of number (float or integer). What the code above does is either use %N or %s as the format depending on whether it's a number or not.

    Your second code won't work because it either gives a format which has two format strings, but only one argument, or it returns nil (if not a number) which will give the type template error.

    Kind Regards,

    Andrew.
