[users] How Do I Combine 2 Text Files - With Different Margins?

[John Gilchrist]

I want to combine 2 Writer text files.
I want to combine file A and with file B.
You know, concatenate 2 files.

Here is the real objective.
File A has page margins = 1.00" Left and Right.
File B has page margins = 0.79" Left and Right.

So, another way to get what I want would be to have page margins A for the
first n-pages.
Then, have page margins B for all pages after page n.

Please.  How can I do this?

Thank you,
John Gilchrist
