I've got an object method that processes transactions from an odbc data source (using the SQLExec function and its cousins) one at a time.

At different stages in the processing, I am writing a line to a text file with the following information: Stage, Record Being Processed, Time of Log Entry, and the Value of SYS(1016) at the time of the Log Entry.

Built as an executable (my most recent tests have been in 6.0 - from July MSDN) the value of SYS(1016) increases by about 2.5MB from the beginning of the transaction to the end.

Running in the VFP Development Environment (again 6.0) this value only increases by 14K!

In addition to the logging mentioned above, I have done the following:
Display Status - before and after the transaction... identical in both the EXE and VFP
Display Memory - again, identical
Display Objects - again, identical
