apply a function twice successively with the same input in awk program
Hi !

It is a general question.
When an awk script looks like:
Code:
#! bin/awk

function example(i){
        <body>
}

{
    example(1)          #the function uses input_1 and return output_a        
}

{
    example(2)          #the function uses previous output_a as an input and returns output_b
}1

How can I tell the program to use the same input for both times I use the function and not using the output of the first invocation as input for the second invocation of the function??? Is it doable?

If someone could explain me it would be very nice.
Thanks!
