Andreas,
The code I sent earlier does not count an interval that includes the upper
limit, 10000. If you wish to count it also, then:
local mult = 1.003
local i = 0
while 30*`mult'^(`i') < 10000 {
di as txt %12.5f 30*`mult'^`i' ": " _c
count if dosis_corr >= 30*`mult'^`i' & dosis_corr < 30*`mult'^(`i'+1)
local i = `i'+1
}
Agai, the display statement shows the lower limit of the interval counted.
Tom
