Syntax error displayed when sqlplus is included in a function

Hi,

I am getting a syntax error when I run the command sh -n test.sh for the below script.

Contents of test.sh
-------------------

#!/bin/ksh
function write_to_log
{
MAILCNT=`sqlplus -s user/pwd <<EOT
set feedback off heading off pagesize 0
select count(*) from dual;
EXIT
EOT`

echo $MAILCNT
}
write_to_log

$ >sh -n test.sh
test.sh[8]: 0403-057 Syntax error at line 8 : `<' is not matched.


However, when I remove the function and check for syntax, I don't get any errors.

Contents of test1.sh (with the function commented)
--------------------------------------------------

#!/bin/ksh
#function write_to_log
#{
MAILCNT=`sqlplus -s user/pwd <<EOT
set feedback off heading off pagesize 0
select count(*) from dual;
EXIT
EOT`

echo $MAILCNT
#}
#write_to_log

$ >sh -n test1.sh
$ >


Please help me out and let me know why this is happening... Thanks in advance.

Please note that this is happening only in Korn shell and not in Bourne shell

I have not a clue if this would be right at all, but have a look at changing to ? That is JUST have the EOT on the line.
