Answer 1

Use the print statement in your code to print out values of variables/return values and so on. If you are using gawk, you can use the -W dump-variables[=file] option to dump variables out to a file for debugging. Also, the option -W lint[=value] might be of interest. See the documentation for more. Other version of awk, such as pgawk provides profiling. A page of the sed/awk book on debugging for your reference.
