The first thing you should do is throw the scummy csh in the garbage and use a real shell, sh or ksh.

You example seems to mix comments and shell commands, please put them one per line so we can see them. Or you may have to attach your script.

host_nme varchar2(20);
begin
select instance_name,host_name,parallel into instance_nme,host_nme,rac_status from v\$instance;
dbms_output.put_line(instance_nme||':'||host_nme||':'||rac_status);
end;
/
EOF

>Bad : mod in $.

Reading the scummy csh man page carefully shows this is the bad line:
#echo "$1:`cat ha2.txt`"

You need to change it to:
#echo "${1}:`cat ha2.txt`"

If you used a real shell you could just do:
echo "$1:$(< ha2.txt)"

Hi:

I'm with Dennis. Avoid the C shell! You should read this classic post by Tom Christiansen:

http://www.faqs.org/faqs/unix-faq/shell/csh-whynot/

I would urge you to use the standard HP-UX shell ('/usr/bin/sh') which is a POSIX superset of the Korn shell. For 'root' this shell exists as '/sbin/sh' and is a statically linked binary necessary during boot up when '/usr' isn't mounted and hence the dynamic libaries are not available.

Regards!

...JRF...
