I'm trying to concatenate a list of "N" number of names. I'm aware of the 30
item limitation, but because of the N number of names, I thought I'd try
something,

Here's what I have:

A B
name 1
name 2 =concatenate(b1,b2,", ")
name 3 =concatenate(b2,b3,", ")
name 4 =concatenate(b3,b4,", ")
etc, etc =concatenate(b(n-2),b(n-1),", ")
name n =concatenate(b(n-1),bn,", ")

and this works just fine. I've been able to concatenate up to 86 names
successfully.
What I ran into today baffles me. Today, I had 107 names. in the middle of
the 87th name, it cut off and would not add any additional text.

Example of the last several charachters...
~~~ Fred Smith, Joe Jones, Tom Sm
The line above was repeated for all additional names in the list

Where the last name displayed was Tom Smith, and other names followed.

Fred Smith
Joe Jones
Tom Smith
Fred Furrier
etc
etc

My first thought was that I've run into some sort of text limitation. So I
pasted the value of the last concatenation and got the length of it using the
LEN function. The length was 1387. An awfully strange number to be a text
limitation.

Please don;t criticize the "inelegance" of my solution. I've had to adapt an
existing computed list for a non-excel user to be able to copy and paste into
a text document the final list of names and this seemed to be the simplest
way to do it until I ran into this limitation.

Any ideas what I've stumbled into?
