-forval- is better:

	forval i = 2/100 { 
		local j = `i' - 2 
		rename x`i' y`j'
	} 

Or 

	forval i = 2/100 { 
		rename x`i' y`=`i'-2' 
	}

A -foreach- solution could be 

	foreach i of numlist 2/100 { 
		<same innards> 
	} 

But it has no advantages over -forval-. 

See also -renvars- from the SJ.

I would like to rename/renumber variables of the format x2 - x100 to y0 - 
y98. In other words, I'd like to subtract 2 from the "subscript".
I'm afraid I am still not skilled enough to figure out how to do this with 
foreach and a macro.
