Hi,
As a beginner I may be going a bit above my head!!

After studying and participating at some considerable length in Threads and links to do with using the Evaluate function to speed things up, I thought I understood it. Here are some of those links and Threads. (www.excelfox.com/forum/f22/concatenating-balls-1891/ VBA Trick of the Week :: Avoid Loop for Range Calculations – Evaluate | Useful Gyaan )

. So … the following simplified example File (XL2007 .xlsm)
https://app.box.com/s/pr78mhna00advvhsrmvi
has a Spreadsheet LEFT Function and a Spreadsheet VLOOKUP Function

The results look good! (That is to say wot I expect!) :-

B3=VLOOKUP(A3,$A$16:$C$33,3,FALSE)
B4=VLOOKUP(A4,$A$16:$C$33,3,FALSE)
B5=VLOOKUP(A5,$A$16:$C$33,3,FALSE)
B6=VLOOKUP(A6,$A$16:$C$33,3,FALSE)
B7=VLOOKUP(A7,$A$16:$C$33,3,FALSE)
B8=VLOOKUP(A8,$A$16:$C$33,3,FALSE)
B9=VLOOKUP(A9,$A$16:$C$33,3,FALSE)
B10=VLOOKUP(A10,$A$16:$C$33,3,FALSE)
D3=LEFT(A3,4)
D4=LEFT(A4,4)
D5=LEFT(A5,4)
D6=LEFT(A6,4)
D7=LEFT(A7,4)
D8=LEFT(A8,4)
D9=LEFT(A9,4)
D10=LEFT(A10,4)




I apply this code

Code: 
[color=darkblue]Sub[/color] Evaluate_Left()[color=darkblue]Dim[/color] rngName [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngName = ThisWorkbook.Worksheets("Sheet1").Range("A3:A10")
[color=darkblue]Dim[/color] rngEE [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngEE = ThisWorkbook.Worksheets("sheet1").Range("E3:E10")
[color=darkblue]Let[/color] rngEE = Evaluate("if(row(3:10),LEFT(" & rngName.Address & ",4))")
[color=darkblue]End[/color] [color=darkblue]Sub[/color] [color=green]'Evaluate_Left()[/color]


And get the following:-

Which again is wot I expect.


Now I apply this code

Code:

[color=darkblue]Set[/color] rngName = ThisWorkbook.Worksheets("Sheet1").Range("A3:A10")
[color=darkblue]Dim[/color] rngCC [color=darkblue]As[/color] Range
[color=darkblue]Set[/color] rngCC = ThisWorkbook.Worksheets("sheet1").Range("C3:C10")
[color=darkblue]Let[/color] rngCC = Evaluate("if(row(3:10),VLOOKUP(" & rngName.Address & ",$A$16:$C$33,3,FALSE))")
[color=darkblue]End[/color] [color=darkblue]Sub[/color] [color=green]'Evaluate_VLOOKUP()[/color]


…but get the following:-

. I would have expected that result without The extra If Row() stuff, which I thought overcame this problem.
. can anyone suggest wot is going wrong, or how I obtain the correct results (Using the Evaluate Function for a range)
Thanks
Alan.

Yep.. Got that bit , thanks;)

. Must be some other Spanner in the works
Thanks Again..

P.s.
The VLOOKUP Mega code from Rory gives me no limit.. I am just having trouble with the second of the two INDEX codes he gave me..

The code is in Module “MacroForshg” in this file: (XL 2007) VBA Evaluate Range VLOOKUP and INDEX witm MATCH for shg.xlsm
https://app.box.com/s/4fvdyd23ri6a7vr45nj0

(The file should open in the appropriate sheet (Sheet 5 “LookUpValues”) )

It is basically doing wot I want (The strange result in Row 6 is a strange new problem, not part of my main problem). The main problem is that the code does not seem to work for more than about 3400 Rows. I need it to work for about 7000. In other words if in the code you change lLastRow to a number greater than I have currently set it (3408), then the code does not work.
. Hope that is a bit clearer. It is basically just a shortened version for you from post #55.


Thanks,
Alan Elston

Doc, I'm just not going to read all of that. At a glance, you can't have a lookup value > 255 characters, as I already explained. Good luck, enjoy the snow.

I think you're simply running into a memory issue. Bear in mind that you are attempting some pretty complicated array formula calculations on a large range of data.

OK, thanks Rory.

. I had had a long break with computers until recently, and thought in the meantime running out of memory was nowadays almost never an issue?
…….
. I just took a look at an actual file of mine which was also just working to about 3401 rows with your last Mega Formula. I was also there coincidentally for initial testing just using 3 columns for the Look Up table (A – C), which is the same as I have been using in the simplified example that I prepared for this Thread.
…..I just increased that to A-AL which would include a Look Up Table Array with considerably more data.

Code: 
Let rngCC.Value = Evaluate("INDEX(INDEX(" & wkstPro.Range("[COLOR=#ff0000]A3:AL[/COLOR]" & lLastRow).Address(External:=True) & ",N(IF(1,MMULT(N(TRANSPOSE(" & wkstPro.Range("A3:A" & lLastRow).Address(External:=True) & ")=" & rngName.Address & "),ROW(" & wkstPro.Range("A3:A" & lLastRow).Address(External:=True) & ")-ROW(" & wkstPro.Range("A2").Address(External:=True) & ")))),3),)")

…….. It made no difference to the 3401 Limit. But I guess it is more subtle than that.
. I guess if it is a memory problem then it is an allocated memory space to something in that formula rather than an actual computer limit?.

. Thanks again for all your help. Looks for now that I have hit a brick wall with that last formula. But an interesting one.

. If at any time any other slightly different version of that last formula springs to mind, please post it and I will Endeavour to do justice to it in trying it out (and maybe one day understanding how it works!):
It seems a shame that I am in the right ball park with 3400, as I need 7000, so I do not need an order of Magnitude more. Maybe by chance a slight Variation in that formula would do the trick. I have no chance of coming up with such a formula. I am amazed how You do it?: As I have mentioned previously I have read and been told that such formulas are not possible.

Changing the first range won't make any difference since the formula only uses the third column.

I can't even use 3400 on my work PC - it bombs somewhere around 3200. You'd probably need 64bit Office to get near 7000.

OK, that is very useful feedback****.. Many thanks for taking the time to try it out on your computer. So my assumption may be wrong, about an allocated memory space, and it may indeed be a computer memory problem. My Computers are a bit old. (Acer Aspires and old LG Notebooks all with 32 Bit Vista or XP). Can I do something simple like deleting lots to "free up space" or is it more subtle than that?


Alan

P.s.

**** If anyone out there with a better (64 Bit etc,) Computer can at some time try the code and let me know where it bombs out I think that would be extremely interesting. (All the info and files needed can be found in the summary I did for shg last night in Post #63
