How do I put a conceptlabel in all-capitals?
You need to use the special function
@uppercase — see https://help.clausebase.com/kb/special-functions/#uppercase9
For example, if you have a datafield #customer^name and would like to convert it to all-caps, you can use
Tip: similar functions
@lowercase (= all lower letters),
@capitalize (= first letter capital) and
@capitalize-words (= every first letter of every word in capital).
Can I ask a follow-up question on this one? Is it possible that when a datafield is a repeating list, this special function doesn’t work?
Correct — the @uppercase, @capitalize, etc. only work on individual text-datafields.
If you are treating the repeating list as a list, then those @functions will not work, because they were designed to work with text and not with lists.
(You either have to extract a specific value from the list using the @nth function, or put the clause in which the repeating datafield is used on repeat (via advanced -> repeat clause in Assemble Document).
