I forgot this one.  We definitely need the ability of renaming fields in an
output only file.  (I hope Hans et al are listening.)

LEAVESR is 7 characters - the op code field is only 6.

I have given up debating the merits of GOTO's.  I only use a GOTO to the end
of a subroutine.  If the subroutine name is @@EDIT, the tag on the ENDSR is
always EDIT@@.  However, this still offends structured purists.

We really do need a GOTO *ENDSR opcode.  I would personally be satisfied
with GOTO *ENDSR but again, structured purists would still object.
