<> You have to separate two issues: One is to transfer your initial data so that Stata understands them. Once that has happened, you merely -format- the data without changing them. See -h format- where you will find the command -set dp- which gives you the comma as the representation of a decimal point. Also, as I said yesterday, -format num %9,0gc- will see to it that you get your separator as you want it. But bear in mind, all of the second part only affects how numbers are displayed, not how Stata holds them internally. And yes, to make my code work, change "num" to your -varname-. BTW, the first part of yesterday`s code was T`s idea...

August 2010 12:07 An: statalist@hsphsun2.harvard.edu Betreff: st: destring and set decimal and comma Hi Statalist, I am facing a problem with destring a variable! My variable named "Dealvalue" has 72914 observations. It's type is str14! All observations are numbers. Some of them are missing, some have the value -1 and the rest of them are usually a very big number like 3,834,848.07 (here I have both comma and dot - in other cases "observations" I have either only comma or only dot or another combination different from this!!! Each observation of my variable, actually each value has different number of digits! So firstly, I would like to destring the variable "Dealvalue". I tried it with the below command (I dont know if it is right!) *** destring dealvalue, generate (dealvalue2) ignore (".,") **** The new variable "Dealvalue2" gives me just the values of "Dealvalue" but without dot and comma! dealvalue dealvalue2 72,000.00 7200000 -1 -1 1,164.24 116424 -1 -1 179,857.26 17985726 1,473,464.97 1,47E+08 9,900.00 990000 -1 -1 118,449.70 11844970 Secondly, I would like to set "," as the decimal point and the dot "." as the 1000 separator!! As I understand, I need a command that will start to reed the number from the end and after two digits to set comma and after three digits to set period. Something like this generally! But the value "-1 " is a specific case and need another command! Any idea please?? Yesterday, Martin suggested me the follow: ***** replace num = reverse(subinstr /// (reverse(num), ".", ",", 1)) destring num, replace ignore(.) dpcomma format num %9,0gc ***** Unfortunately, it doesn't work and I am not familiar with - subinstr - and even don'k know what "num" means. Have I to substitute my variable name there? I would be more than grateful if you send me exactly what I have to run with my variable names in order not to be confused and not disturb you all the time!!!
