\usemodule[chemic] is MKII. It has been replace with core MKIV commands.

The syntax has been somewhat rationalized and many bugs corrected.

The example can be reproduced as follows:


\starttext

\startchemical [height=4500,bottom=2500]
  \bottext{$\beta$-D-Fructopyranose}
  \chemical[SIXFRONT,BB123,B4,+SB5,-SB6,Z6] [O]
  \chemical[+LR12345,LRZ12345] [OH,\SR{HO},H,H,H]
  \chemical[+RR12345,RRZ12345] [CH_2OH,H,\SL{OH},\SR{HO},H]
\stopchemical

\stoptext 



Unfortunately, the revised manual still has some errors that I need to
fix...
