** Print top REBOL stack value to the console.

** Notes:
** This function is used for the main console evaluation
** input loop to print the results of evaluation from stack.

** change between releases. This function allows the host
** to print the result of processed functions.
** Marker is usually "==" to show output.
** The system/options/result-types determine which values
** are automatically printed.
