BEGIN {
number = sprintf("%013.13s", "730003001000")
print number
}
MAWK (Klabaster version) and TAWK print "0730003001000",
while GAWK prints " 730003001000". Which one is correct?

more sense, IMO. The shell builtins of ksh/bash/zsh behave similarly, BTW.
/usr/bin/printf complains about that conversion specifier combination in
context of %s, but not in context of %d.)
If your intention is to pad leading zeroes to numbers use %d instead of %s.
