Dear Nicki, Just set the type of data to STRING,then "0" will not be ingored.You can connect several strings directly.so:

v1=2 v2=105 v3=27 v4=7

V5=v1+v2+v3+v4=2105277

note that v1-v5 are all strings! of course u can input "0" in the fields and they are all identified as strings. also you can try function string(), which can convert interger to string.

regards, Justin

In creating my chk file, I need to ensure that four of the variables contain a certain number of digits. I know this is normally controlled by number fields the .qes file. However, in this instance I need zeros to be included at the beginning (eg. 0003) so that all responses contain the same number of digits. This is because I will be putting these 4 variables together to create a 10 digit identifier later in the chk file. At the moment, whenever I enter 0003, the zeros are removed and I am left with just 3. Does anyone know if there is a way to ensure the zeros remain, and to ensure that each variable entered contains 4 digits? Many thanks in advance for your advice!

Why doesn`t it work like this? v1=2 v2=105 v3=27 v4=7 ident= v1*1000000000 + v2*1000000 + v3*1000 + v4 = 2105027007 (with 3 digits/variable) Regards Juergen epidata-list@lists.umanitoba.ca schrieb:
