Has anyone heard of issuing a number of alter tables against a table that has been created by a "Select ... Into Table ... " causing problems or bombing out.

The table I create is about 178000 records.
I then re-open the table exclusively.

I issue the following
1. Alter Table ...
2. Alter Table ...
3. Alter Table ...
4. Alter Table ...
5. Alter Table ...

Sometimes the program bombs on .
Sometimes the program bombs on .
Sometimes the program works fine.

In one example with a step on inside of my Error method, the table has been closed sometime between line 3 and line 4.

I thought I was dealing with an out of memory problem but I am now logging the memory right after the error and the memory seems fine.

The program works fine on small data sets. I have never seen problems with the smaller data sets. But with the large data set, about 1 out of every 3 runs, the program fails.

I am running VFP 6.0 SP3 on a Windows NT Server SP4.
I have been able to duplicate the problem running an app within FoxPro.

Please Help!!!!!!!!!

TIA
