*$error*

When an error occurs, the script will jump to :error and continue running, [[$error]] will return the error message.

*Example*

<pre>
alias Example {
  ; Add a intentional error.
  noop $hget(

  ; Add a :error label to catch the error.
  :error

  ; Print the error caught.
  echo -ag The error is $error
}
</pre>
