Proper Cleanup of Variables in VFP 6.0

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance

I'm developed .NET apps for the past 2 years and now I'm working with my
first VFP6.0 application. In .NET, you can keep your programming 'clean' by
setting the value of non-managed resources = NOTHING. I've noticed in VFP
you can specify that your variables are 'released' by typing "RELEASE
variablename". Are these two functions essentially the same? Or are they
different?

Thanks.
