  13. I have a need to use a variable where the name of the variable is itself a
  14. variable.  For example, if I have the name of a variable in var_name, I would
  15. like to be able to    echo $$var_name.  However, I can't figure out the correct
  16. punctuation.  Can anyone help?

  18. Thanks in advance,
