PS: with

% engine=luatex

it works fine. Add \relax after the last skip value, i.e.

\spaceskip = 1pt plus 1pt minus 1.5pt\relax

LMTX allows multiple plus and minus values for a skip value and the M in Matilda starts the scan for an additional minus value. Wow, this sounds interesting. Is there an example of how to use multiple values? I think the only examples are in mails from Hans. When you set multiple plus or minus values (as far as i remember) only the last setting is used and all previous ones are ignored. Maybe in some article. Anyway, here is an example:

\starttext test \skip0=10pt plus 10pt minus 10pt plus 20pt

test \skip0=10pt plus 10pt plus 20pt minus 10pt

test \vrule width 10pt height 10pt depth 10pt depth 10pt height 10pt

% test \hbox to 10pt to 10pt {x}

\stoptext

compare pdftex and luametatex.

ok. but why does this run fine \starttext Test \spaceskip = 1.0pt plus 1pt minus 1.5pt Wolfgang \stoptext while this ends in an error message? \starttext Test \spaceskip = 1.0pt plus 1pt minus 1.5pt Matilda \stoptext Steffen
