Title: change case of variable names

I have a data set with about 600 variables and all are in upper case.  Is there a simple way to make the case lower?

I played with ren ARM lower("ARM") that didn't work.  I suspect I'm missing something very obvious.  What I'd eventually like to do is something like

foreach v of varlist A-Z{

ren `v' lower(`v')

}

but that won't work.

Thanks for any help.
