[EpiData-list] Consistency in number of digits

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!
