Hi, I tried typing:

foreach var in x y {
replace `var'[_N]=0
}

then it considers [_N] a "weight" when clearly I want it to just change the last observation of both x and y to be zeroes.

alternatively, I tried the inner line as: ( replace `var[_N]'=0 ) and then it doesn't recognize var[_N] and thinks that it is an entirely new local reference.
Is there a correct syntax here, or does it look like there is some other sort of mistake in my coding ?
thanks,
Florence
