Hi

For the past year I have had trouble with intermittent C5 errors in an VFP 7.0 application. It has taken alot of work to find the cause but I am now a little closer. The problem also occurs in the VFP 8.0 beta because I tested it also.

It appears that VFP optimization has something to do with the problem. I had the following lines in a method which often experienced a C5 Error:

 Scan For PID=ARTrn.ID.And.!EoF()
    Delete Next 1
 EndScan

I changed the line to :

 Scan For PID=ARTrn.ID.And.!EoF() NoOptimize
   Delete Next 1
 EndScan

(I realize that I do not need the !Eof() clause it is a habit from the pre-scan days of FoxPro.)

Since I have made that change to turn off the optimization I have not received a C5 error in 17days and counting. Previously I would see some every week.

Is this a known issue or has anyone else experienced this problem?
