Large table freeze - program crash

Hi there
I have a large table that I would like to freeze (cols > 5000) as a result of a covariance analysis. The program calculates all correlation factors but crashes when I try to freeze the results. I have tried to execute from code with same results. Here my questions:
- Is there a table size limit?
- Is there a workaround for the problem (if known)?
Thanks in advance

What operating system are you using?

The problem is that the 5000 x 5000 sym matrices that have to be created are using too much memory and Windows doesn't like when we try to access that much memory (I'll see if we can be better about gracefully handling it, but it's sometimes difficult to get Windows to cooperate). You could try to increase the amount of virtual memory on your system, play with the advanced memory settings and do things of that sort, but those are likely to be slow and may only postpone the inevitable. Realistically, I suspect that the only way to do this is to use 64-bit Windows and EViews.
[edit] I know that this doesn't help you, but the 7000 obs x 5000 variable case works fine on my Win64 system, but as you note, has problems on a Win32 system. I haven't had a chance to play with my virtual memory settings to see whether I can get it to work under 32-bit.
