I need to know how VFP50 handles local vs private memory variables. Do you have to expicitely release them to free up the memory before the routine goes out of scope ? I have a rather complicated function that handles incoming DDE messages. Over the course of several hours its buiding up the amount of user allocated memory (returned by SYS(1016). I've declared all the variables as local and am explicitly releasing them each time after the routine runs. Dos VFP not free up memory when running SQL queries or something like that ?

I've tried stepping through the code and watching the sys(1016) value on each line but it tends to vary wildly.

I'me aslo using the sys(3050) function to set the size of the buffer that VFP uses but I'm not at all clear what it actually does.

Thanks in advance !!
