David,

I ran your code and did NOT get the same results as follow:

Notice how my memo files are going up in size where yours did not. Now I notice that your version of VFP6 does not seem to have SP3 applied. Is this correct? Your version is : (SP2????)
Visual FoxPro 06.00.8471.00 for Windows [Apr 16 1999 03:38:21]

Where mine is : (Definitely SP3)
Visual FoxPro 06.00.8492.00 for Windows [May 7 1999 17:04:59]

Could this be the problem?

I ran my test on a W95a P200 88MB ram.
