I am learning VBA for Word and need some help please.

I need to break a bunch of large Word documents into multiple smaller documents using VBA. The original files will remain unchanged. The bookmark names are always the same and they are just place markers within the documents.

The documents look like this –

BookmarkA
.
.
.
BookmarkB
.
.
.
BookmarkC
.
.
.
Etc.

The result should be –
File1:
BookmarkA
.
.
.


File2:
BookmarkB
.
.
.
BookmarkC
.
.
.

Would someone please help me get started with this code? Thanks for any help.
