Create unique IDs

User Salimatou has sent us the following question:

Am currently designing a questionnaire for a survey and I would like to create unique IDs for each person to be interview. Is this possible in survey solutions?

A no fuss solution is to use @rowcode.

The @rowcode variable allows accessing the IDs generated automatically by Survey Solutions from the syntax. Hence, the answer is yes, possible and no need to do anything at all for this to happen. But if you are not happy with the default IDs, you can generate you own by utilizing the @rowcode as @gwelch writes. The default IDs are going to be generated anyways and will be used throughout in Survey Solutions where necessary, e.g. in the linked questions.
