pb with grep

[Salah ABOUFARID]

        Hi,

I just install gnv in a VMS machine 7.2 . 
When I use grep and I redirect the output in a file,
the file created is bad. There are only one column. 

command:
grep 'opsp' login.com > res.txt
cat res.txt

result:
o
p 
s
p
s
e
r
v
e
r

However, if I don't redirect the output, the result is good.
command:
grep 'opsp' login.com
result:
opspserver

How to resolve this problem. It is a bug ?
Thank you for your help,

        Mr ABOUFARID Salah
