-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.
