you could only call another script from inside the awk script.

this is basically impossible. environment variables are inherided by
children, but cannot be given back.
a nice workaround for this is something like that:

#! /bin/bash

bashfn() {
  eval $(awk '{print "var=val1 var2=\"this is a value\""}')
}

bashfn
echo $var $var2


works pretty well ...
remember to export the variables, if they need to be inherited by called 
progs.

good luck!
