Print()
The Print() rule sends information to
the standard output, but differs from PrintRecord() in
that the information to be printed must be specified.

The Print(); statement
uses following syntax.
Print ( string, [optional list of variables] );At
least two comma-separated arguments must be specified within the parentheses
of Print(). The arguments can be any of the following:
a list of strings enclosed in quotation marks (which may be empty),
a string that is not enclosed in quotation marks (which may be a symbol
definition name or may be NULL), an integer, or an eval statement.
