TAWK has true local variables, which is very nice, but in "standard"
AWK it is done via a (widely accepted and practiced) kludge. See below.

The idea is that you declare your funciton like this:
function foo(arg1,arg2, tmp1,tmp2,tmp3) {}
And then call it with only 2 args. The additional args get initalized
to "" (as if they had been passed by the caller as ""), and act like
local variables in the function.
It is also conventional to separate the "real" args from the fake args,
with whitespace, as I have done above.
