The goto operator is "-> label", while

I overstated the case. However, goto is in fact "-> expression", where
expression is an integer scalar referring to a line (implicitly numbered
from 1 upwards) of the current definition; a goto to a nonexistent line
such as 0 exits the current definition or program. Labels were added
later, and are essentially local variables bound to the line number they
appear on. Modern APL uses structured-programming constructs like all
other post-Ratfor languages.

One of the oil men in heaven started a rumor of a gusher down in hell. All
the other oil men left in a hurry for hell. As he gets to thinking about
the rumor he had started he says to himself there might be something in
it after all. So he leaves for hell in a hurry. --Carl Sandburg
