This leaves me with a slight problem.

I have on the new Mac many files that I made with pages. They all carry the .pages extension of course.
Open Office won't open them using the .pages extension and I really don't want to have to change each file to Microsoft Office if I can avoid doing that. (Many files involved)
Is there any way at all that I can solve this using Apple's software and Open Office?????
Many thanks;

If it helps others, my solution was to try everything suggested. It is notable that I do NOT have Pages installed on the Mac during the period involving this issue. The .pages issue had to be handled without Pages on the system.
The result (for me personally in my situation) was to gather the .pages files that needed to be dealt with and put them in a dedicated folder on the desktop. Those that were NOT requiring future editing were changed to a PDF format through the print dialog drop down and refiled. Those needing editing down the line were simply (restructured) as a new file in OO by copying the text into a new document and simply inserting imaging where required. These files are now stored as OO files and can be converted to any available extension required at the time they need to be emailed.
I deeply appreciate your help as a group and look forward to future dialog with you as situations require.
