fatal: function name previously defined

Question

For the listing below, I get an error:

fatal: function name `myprint' previously defined

$3 > 0     { myprint ($3) }

function myprint(num)
{
    printf "%6.3g\n", num
}

Answer 1

I discovered that I had an extra space after the call and between the parameters:

myprint ($3)

should be:

myprint($3)
