The following MWE gives "false false" instead of "false true". I'm sure this

Do you want cake? \datasetvariable{somedataset}{1}{wantscake}.\\

Many thanks for your reply, Aditya.
Your approach is really interesting, but I don’t know how to mix i
is? The new information can lead to
an extra line-break or extra page-break, which might then need an extra run to
resolve correctly. So, it might be better to ask the information in the first
run and save it in the tuc file using the two pass mechanism:

One and a half question.
Why did you set \ChapterCounter explizitly and why is \ChapterCounter
part of the datasetvariable?
\dataset... is a high level interface for collecting two-pass data in ConTeXt.
Here is a simple example:

Hi Wolfgang,
thank you very much. Amazing!

the "reset" key is used before the values in
\setvariables are stored while "set" is used after the values are stored.
I don't understand it. Has it something to do with "Command/datasetvariable"?
No, this is a different mechanism to save values between different

Hello Wolfgang,

The references are on different pages.

This is what I've tried, but it is always the currentdate, that is
displayes.
You are trying to use the date before it is defined. You can use a
two-pass mechanism:
\define\mydate{\datasetvariable{mydata}{date}{date}}
Thank you Marco, this works.
Is it possible to update fields in the datasetvariables
