Borland DOS Applications

I remember there was a patch (upon request to borland, because ...yes, I was a registered user but I knew about the patch from other people, not from borland) named 7.01.
Borland used to put the version in the time field of the files,
so if you have a "genuine" version you should see all the files with a time of "7.01".
The patch was the same for both turbo pascal and borland pascal, a.k.a normal and professional edition.
I have no info about the turbo c because I was not using it at the time.
Bye everybody.
