Dividing by zero in a BEGIN rule (or some other
non-END rule) will cause the program to terminate
immediately without invoking any END rules.  You
lose the ability to explicitly set the return
code.

Arnold Robbins added an abort() function to the
gawk extension library.  You can pass a parameter
to abort() to set the return code.  For details,
check the list archives for January, 2018 for a
thread with the subject "abort keyword".
