Interesting.  This fixes it in beta but not in TL17.


side floats are redone recently ... so partly incompatible code with TL17


BTW: What snapshot is going to be in TL18?


i might push a current

In the manual is an example on page 233 with the following content:

-

\def\rotatetokens#1#2#3#4% delta extra radius tokens
{\vbox\bgroup
\MPtoks\emptytoks
\resetMPdrawing
\startMPdrawing
picture pic[] ;
numeric wid, len[], rot ;
numeric delta, extra, radius, n, r ;
len[0] := n := 0 ;
delta := #1 ; extra := #2 ; radius := #3 ;
\stopMPdrawing
\handletokens#4\with\processrotationtoken
\startMPdrawing
r := len[n]/Pi ;
for i=1 upto n :
wid := abs(xpart lrcorner pic[i] -
xpart llcorner pic[i]) ;
rot := extra + delta -
((len[i]-.5wid)/len[n]) * (180+2delta) ;
draw pic[i]
rotatedaround (origin,-270) shifted (-r-radius,
ypart -.5[ulcorner pic[i], llcorner pic[i]])
rotatedaround (origin,rot) ;
endfor ;
\stopMPdrawing
\MPdrawingdonetrue
\getMPdrawing
\resetMPdrawing
\egroup}

\startcombination[3*1]
{\rotatetokens {0} {0}{0}{Does it work ok?}} {A}
{\rotatetokens{20} {0}{0}{Does it work ok?}} {B}
{\rotatetokens{20}{30}{0}{Does it work ok?}} {C}
\stopcombination

But I cannot see what part calls what parts and how they can be
embedded.

Thank you very much for these examples. The most important hints are
given now. Perhaps I am able to apply them.

One misunderstanding made by my post: I want to write the text curved
as a (half-)circle.

I want to place text in half circles of various radiuses. Is there
