FTP from AS400 to Mainframe

Hi,

We are trying to send the an IFS document to mainframe system through FTP. 
Though the transfer is successful, the target dataset in the remote machine is 
getting appended with the userID with which we have logged on in the FTP 
session.

After consulting the mainframe programmers we introduced the quotes(single) 
around the dataset name and included the subcommand QUOtesoverride. But the 
result is same.
However,same specifications work very fine when I try to transfer from DOS 
prompt.

These are the command I have used in the FTP session 

UserID
Password
Namefmt 1(For HFS)

QUOTE SITE CYL PRI=200 SEC=50 RECFM=FB LRECL=550 QUOtesoverride (This is to set 
the space/rec fmt length in the remote system)

PUT /QDLS/mydoc.txt 'dataset name'

After this the target dataset name gets appended with the userID 
(UserID.dataset name)

Can anyone suggest/help on how to go about this.

Thanks
Vishnu
