SCCS problem when copying files

I have created a SCCS directory with version 1.1. It has say A.txt (for simplicity)
Now updated files are present in other directory. If I copy A.txt it wont be effected in SCCS. How do I make this A.text to be version 1.2??
Please help!

It's been 20 years or so since I've used SCCS, but I think it's just...
get -e a.txt
cp /source/directory/a.txt .
delta -y "copy from /source/directory" a.txt
... or something like that.

Thanks much....
It really helped!!

By default it makes 1.1,1.2,.1.3
I want to make 1.1,2.1,3.1 etc
How to do that?
