You can use variables or any expression, eg
printf(fn,sprintf("%%0%dd",colwidth),val), or
printf(fn,"%0"&sprint(colwidth)&'d',val)

Suppose you have eg  printf(file[i],format[i],valueset[i]). It should
be perfectly legal for this to reduce to printf(1,"hello",{}). Hence
there is no absolute need for the format string to contain % at all.

I would agree that the format string should contain the same number of
valid format qualifiers as the length of the 3rd parameter, but Rob
has already stated he will not do this. If you want better error
checking you'll have to wrap printf yourself.
