how to remove a single file from sccs repository?

why would you do that? i.g. you never delete something in the repository.

Said this: deleting a file in sccs' repository is very simple:
  rm /path/to/sccs-repository/s.your-file

I want to remove the file from the repository because I feel that I am not able to check in my latest modification.
I did the following:

1. sccs edit file
2. modify file
3. sccs delget file

The last command asks me to put a comment and looks like everything is good.
But when I do the following

4. sccs diffs file : I see the old changes still. My understanding is the diffs command shows the difference between your file in the current directory and the one in the sccs repository. So if the changes were checked in, there should be no diffs output.

5. sccs edit file : This one supposed to have checked out the latest from the repository. But when I open theis file, I see the one before the modification.

Please Note: I originally checked in the file ( first time ) from the production box by mistake with : sccs create file
Later I tried to update the changes from the development box with : sccs delget file. I never did a : sccs create file from the development machine.
