Exit from aips, do the setenv above (or export MYY2K=/home/miao/Y2K if
you use bash shell) - then test it with
        echo $MYY2K
        ls -l $MYY2k/*
then , if these show the expected results,
        aips
and procede.  You cannot do a CTRL-Z, set a variable, and then do fg to
have aips know the meaning of that variable.
