```Try this. It's probably not the most efficient way, but it should work.

********************************************************************
/* Given a variable named x, this loop will create a variable
named y that will be labeled with the information you want */

gen y=.

local i=1
while `i'<3 {    /* You should change the 3 to what ever your max
value for x */

local j=`i'+0.05
local k=`j'+0.05
local n=round(`i'/(.05))

replace y=`n' if x>=`j' & x<`k'
label define ylbl `n' "`j'<=x<`k' ", modify

local i=`i'+.05
}

label values y ylbl

tab y
