To work around the column limitation can you link to a column in another sheet? Send row IX data to Sheet2 column A1, for example and use that in the interpX call?

I've thought of that, but my Excel workbook already has well over 20 sheets. It's getting way too hard to manage, that's why I upgraded to Excel 2007. I had already run out of fonts in Excel 2003, and I thought the additional fonts & columns in 2007 would be a godsend. There has to be a way to upgrade the Interp32.xll addin with an updated InterpX that will allow the use of the additional columns available in Excel 2007. Hopefully the Gentleman (JChampion) that created Interp32.xll will read my frustration and apply his expertise to upgrade the addin. I'm sure the "X" number of scientists and engineers using Excel beyond its limited capabilities will be appreciative.

I haven't had a chance to download and look at the source, but the limitation could very well be hard-coded. You can email the author directly (look for one of his posts and then click the Email link) or you can also post a reply under the article (it should notify him). Maybe he can shed some more light on the limitation problem. I seem to be out of solutions/suggestions at the moment.

Had a quick look at the source. There's quite a few places in there where the limits are defined as 255. I think this line from Xlcall.h is the important one though:
#define xlUDF 255
From MSDN:
xlUDF
Calls a user-defined function (UDF). This function allows a DLL to call Visual Basic for Applications (VBA) user-defined functions, XLM macro language functions, and registered functions contained in other add-ins.
[...]
Zero or more arguments to the user-defined function. When you are calling this function in versions earlier than Excel 2007, the maximum number of additional arguments that can be passed is 29, which is 30 including pxFnRef. In Excel Microsoft Office 2007, this limit is raised to 254, which is 255 including pxFnRef.
Looks like it could be hard-coded into Excel itself. Now, I'm not an expert on this but if you are trying to pass cell references beyond the 255 column limit this could be what is causing the problem.

This Call seems to have corrected the max number of arguments issue but not necessarily a column limitation... Excel 2003 and versions before have 256 columns (0:255). Excel 2007 has 16384 columns and I expect that it is the limitation keeping InterpX from working. So I guess you're on the right track. Maybe there is another 255 imbeded in the code elsewhere.
Also, there is a microsoft site
http://msdn.microsoft.com/en-us/library/aa730920.aspx[^]
that addresses some issues with "Developing Add-ins (XLLs) in Excel 2007".
If I had the time and inclination I would tackle this issue, but with my current workload that isn't possible. If you know how to contact the original author of the InterpX function & Interp32.xll article (JChampion), maybe he would again tackle the mods needed to enable his Interp32.xll to work in Excel 2007.
Again, thanks for any and all your help.

"Math-making seems the opposite of automatic, which is why scientists long thought it had nothing to do with our ancient, pre-verbal size-em-up ways. Yet a host of new studies suggests that the two number systems, the bestial and celestial, may be profoundly related, an insight with potentially broad implications for math education. "
NY Times article[^].
An interesting article from the New York Times about the human capacity for mathematics and its implications for math education.

That was pretty damn interesting. I like the 'bestial' & 'celestial' thing they had going there, kinda reflects how I feel about it. I also took their coloured dots test and I got 100%.

It's hard to find articles like that. I usually get them from the NYTimes or the CBC.
Speaking of the CBC, you may enjoy their science program, Quirks and Quarks[^].
Glad you enjoyed that.

No problem - it's a very good program, award winning even!

can anyone tell me the algorithm for the pseudo random number generator? and how it works, i tried searching the net but to no avail..
thanks in advance,

Hey, I don't think that six you rolled is completly random. Since there are more pips on that face than the opposing face (one), it likely be up more often than not.

Not really; they're only one-sixth as deep as the one on the opposite side.

I know, but the mass distribution is different.

Okay, so I was guessing...
But seriously, it's only one part of the equation. On the pair of sides showing 6 and 1 pip, one can consider that a shift in the center of mass occurs equal to some distance proportional to the ratio of the mass of one pip to the entire die in the direction of the face with 1 pip. Call that distance (6-1)l = 5l, and its direction i .On an adjacent face, the 5 counters the 3 for a distance of (5-3)l = 2l in the direction j. Normal to the plane formed thus is the pair 4 and 3, at a distance l in the k direction. The total distance by which the centroid shifts is then sqrt(25+4+1)*l = 5.477*l. Its direction is left as an exercise for the student, but it is decidedly not toward the face showing a 1. Remember, too, that we can't just rely on the measure of missing plastic in the pips, but must add back the mass of the paint used to mark each, and that might have a specific gravity much higher or lower than the base material.
For practical purposes, the amount shift in the center of mass is negligible compared to the random variations in surface texture of the felt on the table, and the influence of random air currents from breathing, talking, air conditioning, passers by, and the occasinal fart. 
The outcome is close enough to random for any engineering use, though a mathematician might argue the point.

Hey, you're definitely cheating: my (pseudo ) random device rolls in a vacuum box!

Well then, I guess the only way to resolve the matter is for you to build your machine, then run it through 6^(6^6) iterations and see if the Universe ends.
