Hello, Lua way: ---- \setuplabeltext[chapter=] \define[1]\MyCommand{\ctxcommand{doifelse(1==\currentsectioncountervalue)}{ONE}{#1}} \setuphead[chapter][deepnumbercommand=\MyCommand] \starttext \chapter{Cool} \chapter{Cat} \chapter{Mouse} \stoptext ---- I'm sure there is also a "cleaner" TeX way, but I'm not experienced enough for that.

Any idea for achieving this behaviour?

- When there is a chapter label (\setuplabeltext[chapter=CHAPTER~]), display :

CHAPTER ONE Cool CHAPTER 2 Cat CHAPTER 3 Mouse etc.

- When there is no chapter label (\setuplabeltext[chapter=]), display:

1 Cool 2 Cat 3 Mouse etc.

My try achieves the first display, but not the second one since I don’t know how to test the emptyness of the chapter label. When I remove the chapter label, it displays:

ONE Cool 2 Cat 3 Mouse

instead of:

1 Cool 2 Cat 3 Mouse

My code:

\setuplabeltext[chapter=CHAPTER~] \define[1] \MyCommand{\doifelse{\currentsectioncountervalue}{1}{ONE}{#1}} \setuphead[chapter][deepnumbercommand=\MyCommand]

\starttext

\chapter{Cool} \chapter{Cat} \chapter{Mouse}

\stoptext
