I was going through usenet (microsoft.public.fox.programmersexchange) and saw someone mention that there is an undocumented SYS(1104) call that purges unused buffers. My VFP .CHM doesn't mention that call, and doing "=Sys(1104)" at the command window (VFP6/SP5) doesn't return an error.

So what gives? Is anyone using this? Any benefit?
