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!

A solution could be:

Code:
awk -f a.awk infile

where a.awk:

Code:
function example(t, i) {
    if (t==0) {return "<font>call " t ":" i "</font>";}
    if (t==1) {return "<font>call " t ":" i "</font>";}
}

{
   print example(0, $0);
   print example(1, $0);
}

Hi rdrtx1, thanks for your help !

I'm not sure about <font>call, what is that ?

It was just an example of output to html not a call. In the example code it looked like you were working to build html output.

Nope not working on html.
So any idea how I could do that?

That opens up a whole can of worms. The awk reporting language can be used to build any type of text file.

You need to make your question a lot less vague. Sample input and output would be good.
