Three Word files open on screen at the same time Mac OS X

[Dave2002]

I have a specific problem, which is causing my hair to fall out faster than normal.

I want to have three files side by side on my screen. All are in Word. All are quite large.

File 1 is an original version.
File 2 is an edited version.
File 3 is a comparison version

This may be possible in Word 2016 in Sierra or El Capitan. I don't think this is easy on the machine I'm currently using.
To my amazement the version of Word only seems to have a horizontal split - not a vertical one. I think the latest version of Word I have is 2011.

There are work arounds, such as generating PDF files from each, and then displaying those but at some point I might need to edit.

Quite frankly I'm beginning to wonder if it would be easier to just print out the whole thing on paper - several versions (total currently about 200 pages - for a 60-70 page document) and work the whole thing out the "hard" way. This could be a problem where the "fast" way - using a computer and paperless - actually turns out to be orders of magnitude slower than using older techniques involving printers and chopping down trees, together with highlighter pens.

I'm not sure if the phrase "can't see the wood for the trees" is apt but this is sure one heck of a mess.

Not really understanding how you want to use the three files simultaneously. As you scroll one forward, you want the other two to be scrolling forward at the same time?

Good point, bur I expect I could manage doing the individual scrolling. Right now I'm exploring other possibilities, and a different approach, so this might not be necessary this time.

I was wondering because on my iMac I can have three files open at 100% possibly a shade more (Word 2016 has a slider). Not sure what the 'comparison' does. It all sounds a bit complicated, but then I usually just make a copy and edit that without needing the original open. Still less a third - but I don't use notes and stuff like that.
