I'm trying to have the date in a layer in an environment. In the

If the date is not set, the current date should be used, otherwise
the set date.
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 table, or is it
only possible to replace the whole table?
\setdataset[data][info][date=\currentdate]
\setdataset[data][info][subject={subject}]
After the second line, the first value is gone.
Thank you,
Ingo
