Shell Programming and Scripting

I am using the following script. I am basically trying to enter data to my database using a storeprocedure.

PFB MY script.

Code:

#!/bin/csh -f
foreach FF (`cat ADDUSERS`)
isql -VENKIDB -U gloss -P glosss << _endl
set nocount on
go
use VENKI_PROD
go
print "Adding the user to GSTB Institutional for User : $FF"
go
sp_addlogin '$FF', '1$FF'
go
_end1
end

The script basically takes values from another file which is passing the values one by one as a parameter.

However when I try execute the above script it fails at second line with the below error.

_endl: << terminator not found

I tried various options and could get it corrected. Can someone help in finding out , what exactly I am missing.

Thanks in advance for your help.
