Andreas,
The following code should do what you want:
local mult = 1.003
local i = 0
while 30*`mult'^(`i'+1) < 10000 {
* di 30*`mult'^`i' ": " _c
count if dosis_corr >= 30*`mult'^`i' & dosis_corr < 30*`mult'^(`i'+1)
local i = `i'+1
}
If you wish to see the ranges being counted, remove the asterisk (*) on the
display statement
Tom
