Print Expression
There are several printing statement forms.
print expression { , expression } ;
prints the values of the given expressions on the standard output. If more then one expression is
given, they are printed with a single blank separating each item. print does not put a newline
character at the end of the output.
println expression { , expression } ;
is similar to the previous format, but does print a newline at the end of the list of expressions.
print expression { , expression } -> filename ;
println expression { , expression } -> filename ;
are similar to the other printing statements, but they print to the given file instead of to the standard
output. The filename is given as a string-valued expression. If the file does not exist, it is created; if
it already exists, output is appended to the end of the current contents.
