SAY [expression]

The expression is evaluated and displayed on the standard output,
followed by a newline character. If no expression is supplied then just
the newline character is output.

LOCAL: The command:  SAYN expression
       evaluates the expression and displays it without a newline
       character.  Note that a similar effect can be obtained with
       the function call charout, though the output may have to be
       flushed by calling charout a second time with no parameters.
