The code is text. There are a variety of text comparison tools out there, so you can probably find a free one that you like which will show you the differences between A and B. Aside from that, you may not have any alternative in VB6. If you can open two versions of VB6 simultaneously, you could open one sub in one version and the other sub in another version, then you could put them side by side.
Yeah, I know about using two of the same projects.
Right now I copy Sub2 to a new BAS module then compare Sub1 in the original module to Sub2 in the new module, make whatever changes need to be made then copy Sub2 back to it's original location and delete the one in the new module.

I thought WINDIFF.exe was part of the VS install - I've always had it around and use it quite frequently. It compares two text files (or two folders of text files) and displays the differences very nicely.
Actually - I just looked on an old XP machine and it's part of the Microsoft SDK for v6.0A
And it appears to be available for Win 7 and later here

I'm looking for way to see two subs side by side manually. There will be many differences which are OK; but I need to see if each sub has the same processing methods even though names will be different. For example one Sub is called ProcessWhite and the other Sub is ProcessBlack. They both have to do the same thing with the same methods and API calls and whatever but each Sub will refer to the objects and arguments as white and black (ie WhitePiece, BlackPiece, Call GetWhiteInfo, Call GetBlackInfo, etc)

The code windows have a splitter that allows you two have two views of the same module, but they are arranged "over and under" rather than "side by side."
Until wide aspect ratio monitors came along "side by side" didn't make much sense. This is probably why older tools like WinDiff don't have such a mode either.
If you want to do this and can consider using another text editor for it you might look at:

That is exactly what WINDIFF does - it compares two files and shows similarities in WHITE text and differences in RED (old file or file on the LEFT) and YELLOW (new file or file on the RIGHT). And a HUGE summary GRAPH on the far left - it's very comprehensive (although not as good as the DIFF utility from my mainframe VAX/VMS days).

Yeah - I know that - I worked that line since I was 17 years old. I figure most folks here would not know what a minicomputer was. Obviously you are old enough.
Er? Do you make that noise often? I'm glad I'm not in your actual presence!

omg - I just logged into a VAX right now? Do I use my minicomputer or mainframe commands? Oh - I don't remember - better ask Dilettante!

I guess I can handle these older tools - WINDIFF included!

The VAX went through many different implementations. The original VAX 11/780 was implemented in TTL and filled a four-by-five-foot cabinet[6] with a single CPU. CPU implementations that consisted of multiple ECL gate array or macrocell array chips included the VAX 8600 and 8800 superminis and finally the VAX 9000 mainframe class machines

Some of us spent major portions of our careers working with large machines, many of them dwarfing even the largest VAX 9000 ever shipped.
It is too bad some people have no experience with actual big iron. And far from "dead" you might be surprised at how much mainframes are still in use today.
Not only side by side, but two subs in the same file.
Most every Diff I know of requires two files, which the OP says is what he has to do currently. Copy the sub to a new file, compare the two files, make the changes to the sub, and copy it back to the original file.
The point was whether there is a mechanism to look a two subs side by side, not two files, in order to eliminate the need to create a second file just for comparisons.
Open VMS 7.2... That might actually be a "MicroVAX", correct?
And regardless of size of machine, I don't think I worried about MainFrame commands, or Minicomputer commands, it was the operating system (i.e. VMS commands) or even the shell (i.e. DCL commands) that you deal with.
Haven't worked with VAXs in quite a while, but it was quite nice when when we got a MicroVaxII to do some development with, as a compile on the VAX-11/785 that took 15 minutes, would compile in about 20 seconds on the MicroVax. Before that we had a PDP-11/34 and I used to do the compiles on third shift for the software engineers and we generally only build one load a day, as it took several hours to build (compile and link) several of the projects that made up a Simulation load, so my DEC period extended from 4 hours to build a particular big program on the PDP to 15 minutes on the VAX-785 to 20 seconds on the MicroVAX. Took awhile to warmup to Unix after doing DEC VMS for 8 years or so.
I also took a look around but I didn't find any IDE add-in permitting two open code windows on the same module. With that he could tile them side by side.

Re: Viewing two pieces of code side by side
but two subs in the same file
Yes, that does seem to be the bit everyone's missing.
To be honest, if that's what you want to do I can't see what's wrong with Shaggy's suggestion. Just open two IDE's. As long as you're making the changes in one IDE only that should be a fairly straight forward solution to the problem.

If they are in the same file, you can use the split view... I think it got mentioned early on... it splits the view into a top/bottom view... I've used it for the same thing, to compare to pieces or when I'm working in an exceptionally long sub and need something at opposite ends. You activate it by going just above the up button in the scroll bar... you'll get the horizontal split cursor when you're over it, click and hold it, then it works just like a splitter... you can make it as big or as small as you want. When done, resize the split so that the top disappears.

The OP said he was using VB6.
VB6 doesn't allow opening the same project in a second IDE session (which Shaggy gave the disclaimer "If you can open two versions of the VB6 IDE simultaneously...").
You can open multiple VB6 sessions, just not on the same project.
Yeah, my memory of VB6 is fading. Of course, in .NET, it would be easier due to advances in the IDE itself. I just forget what was and was not added to the IDE in various versions. Now that people mention it, I do remember using that over/under comparison a few times. It really sucked on rectangular monitors too, unless you had the lettuce for a large monitor. Back in those days, people were often still running 640x480, or possibly 800x600, neither of which had enough screen real estate to do much of a comparison.
As for the debate about whether a VAX was a mainframe or a minicomputer, I could ask my father, as he was a DEC engineer in those days and would probably explain the nuances in great detail. He'd give you just the VAX.
On the other hand, we could put it to a vote by going around asking people about it. It might be considered a Vax populi.

As far as I can tell, Beyond Compare still requires two text files to compare against, it won't allow you to compare two subs in the same file against each other. The OP is currently having to copy the one sub to another file temporarily in order to do the compare, and was asking if there was a way to view (and compare) two subs against each other without having to copy code to another file.
