I am following a thread on a problem with the SUM command in VFP 7. One note by Microsoft is that this behavior will be less likely to occur if the sys(1104) function is used.

I have not previously used this function and I would like to be fully aware of any potential repurcussions of using this function before implementing. One primary question I have: What memory is cleared? Will this lose memory variables, etc.?

Also I have a procedural question: Would it be good programming practice to add this throughout the application, for instance in the Release method of all forms? Refresh method?

Thanks in advance.
