⎕ Output with newline

If ⎕ appears to the left of the ← symbol, it causes the result so far to be displayed. This may not be the result of evaluating the complete line as ⎕ can occur anywhere on the line. The data is output together with a newline (carriage return) character, and is displayed subject to the values of printing precision (⎕PP) and printing width (⎕PW).
