Hello,

I am a newcomer to INTERCAL and I am confused about ick's behaviour
towards programs that do not end with DO GIVE UP.

According to the manual <http://catb.org/esr/intercal/ick.htm#Errors>:
* E129 is a compile-time error triggered when a NEXT statement points to
  a non-existent label
* E633 is a runtime error triggered when execution runs off the end of
  the program

Consider the following one-line program:

  DO READ OUT #1

When compiled, it gives no error. When run, it outputs the following on
stderr:

  ICL129I PROGRAM HAS GOTTEN LOST
          ON THE WAY TO WHO KNOWS WHERE
          CORRECT SOURCE AND RESUBNIT

This seems inconsistent with the manual -- shouldn't it be E633 instead?
Am I missing something obvious or is this a bug?

It should be mentioned that a program where a NEXT statement points to
a non-existent label does correctly give E129 during compilation.

This is C-INTERCAL 0.29 from the Gentoo repos.

Thank you,
