What function is it? How can I execute that function?
The only reasonable answers I can think of are "it's the function
{1⊣⎕←2}" and "you can execute it by typing f and hitting ENTER", but
that's clearly not true because when I type f and hit ENTER I don't
see the number 2 printed to the session:
f
1
Thanks,
Jay.
