  end
end

Can't work logically because you would get first line from first and than you would print out with first_1_line all second lines and not just second_1_line

But thanks.

AWK worked. Just not clear why the filenames can't be overgiven as arguments.

why do you include it in BEGIN{...} section?
Initialize it outside awk!

Code:
#!/bin/sh
fileA=$1
fileB=$2

nawk '
NR==FNR\
{
  a[++i]=$0;next
}
{
  b[++j]=$0;
}
END\
{
  for(k=1;k<=j;k++)
    {
       print "\n======== " a[k] " ========"   
    }
}' $fileA $fileB
