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

Dear All,
I apologise if this question is simple but I really can't figure it out.
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!

Dear Nicki,
how will your identifier look like? 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)
