Left


Two-argument form  See also one-argument form Stop

The function (left) takes left and right arguments of any type, rank and shape. It discards the right argument, and passes the left argument through unchanged.

It can be used as a statement separator, where (unlike using diamond) the actual expressions are evaluated in normal APL right-to-left order:

      x←1 2 3 ⊣ y←4 5 6 ⊣ z←7 8 9
      x
1 2 3
      y
4 5 6
      z
7 8 9
