Hi Dennis,
Thanks for the input. The array size is not any larger, it just loops through finding it many more times.
I have 6 GB of memory on my computer. I am not sure what my variables require. But it loops through finding the values it requires many times before it has a problem. So, there is something building up over time, but it does not make sense to me because all variables are overwritten on the next loop.
One thing that I am doing is appending the results for each loop to a .txt file. Could this be causing some problem?
I attempted to run the program as you specified below, but it does not seem to identify the 'top' command.
Thanks very much for your help,
Lisa

I assume this means the array size(s) are much
larger.
You have run out of memory.
If the primary variable is (say) 6GB and you
have only 4GB,
you will get a 'NclMalloc Failed' error. This
is regardless
if you have deleted all other variables.
Do you know how much memory your computer has
*available*?
Do you know how much memory your main
variable(s) need?
[2] One crude approach
%> ncl lisaAlexander.ncl >&! z.out
&
Then immediately,
%> top
This will show you the memory usage
of your job.
