Re: macro question

[Mike Mackovitch]

No need to mess with $cfilname.

I have a write-hook that saves numbered backups (file~#~, where # is 1, 2, 3, etc.) by

simply passing the filename to some code that makes a copy of the file using the

next unused number and preserving the mod time.

write-hook is called before a file is written (so I don't think it would work
just like the suggested order).

But you could have a macro which decides what the filename should be,
and writes to that.  The macro should save and restore $cfilname,
otherwise $cfilname will get updated to point to the most recently
written file.
