Is this what you mean?
clear
set obs 10
gen x = uniform()*10
set obs `=_N+1'
summ x, meanonly
local max = r(max)
replace x=1 if `max'<2 in l
replace x=2 if `max'>=2 & `max'<5 in l
replace x=3 if `max'>=5 & `max'<. in l

Subject: st: Testing for a particular value and replacing in last observation?
Dear Statalist,
assume there is one variable x with 10 observations filled with
random numbers between 0 and 10.
the 11th observation should carry the value 1 if ANY observation of x
is <2, 2 if any observation is between 2 and 5, and 3 if any
observation is bigger than 5.
I tried the following:
local obs = 10
local count = 0
while `count' <= `obs' {
replace x = 1 if x < 2 in `count'
replace x = 2 if ....and so so on
}
apparently, this does not work as intended, as this loop does not
place the values 1, 2, 3 in the last observation but in the
observation `count'
I actually need an additional "in"
replace x = 1 in L if x < 2 in `count'
Unfortunately, stata does not allow for this systanx
Do you have any hint for a workaround?
Best,
Christian
