Thanks Bill, it worked! I did this before, but unfortunately I left out one step.  Sigh ...

Happy New Year Bill!

Ken. tools/options/projects is the way to reset this value.
1. Start the program.
2. Go directly to tools/options/projects
3. Set the number of cells to 10 million. Don't set the number
of rows, just the number of cells.
4. Press OK and leaves the tools menu.
5. Exit the program without reading the data.
6. Restart the program.
7. READ or IMPORT the data.
8. Use File:Save Project As to save the project.
Now continue your processing. Before you exit the program,
save the project. Then, use File->Open Project to resume the

Has anyone else had this issue, and if so, what was the fix? thank you.

I am having the following problem allocating enough memory to
LIMDEP/NLOGIT6 in order to run regressions. The data set that I am trying
to load contains 24 variables (columns) and 275,875 observations (rows). I
have used import variables and read commands, but the results are the same,
not enough memory to load the data set. I am not a new NLOGIT6/LIMDEP user,
and I have run large data sets with older versions; however, I was able to
set both the cell numbers in memory allocation and the rows in dimensions,
and then the number of columns would adjust automatically.

This is not happening in my version of NLOGIT6 (Sep 7, 2016). I can only
set the number of required cells in memory allocation, but I cannot access
either of the dimensions - rows or columns. Thus I can set the number of
cells to my requirement of 6,621,000; however, the number of columns remain
at 900 while the number of rows adjust to 7,356 - I cannot manually change
the number of rows. The rest of the rows in my data set are then set to
missing data.

I then receive errors 522 (READ needs 6621000 cells. NKMAX= 5000000. Use
Project menu ...) and 7 (READ - Data set is too large. Expand data area

Attempting to reset the memory allocation through project/settings or
tools/options/projects is not helpful.

Any help would be most appreciated.

Thank you, Ken
