Hi Wolfgang,
Thanks for having solved the problem with subformulas numbering.
I would just make a comment on your answers to Lukás, regarding the use of
\startsubformulas[mylabel]
Indeed using this structure instead of
\startsubformulas[+]
allows one to refer to all the sub-formulas by invoking (\in[mylabel]), but if
one wishes to refer to any individual sub-formula one has to give a label
inside the structure \start—\stop—subformulas, at the level of \placeformula
for that sub-formula.
Below is your example, with these remarks.
Thanks for your attention and help: OK
%%%% begin example
\usemodule[visual]
\starttext
Using the definition of the scalar product we infer that:
\placeformula[eq:1]
\startformula
\fakeformula
\stopformula
And here are some other relations valid in a Hilbert space:
%\startsubformulas[+] % These two options for \subformulas
%\startsubformulas[mylabel] % enable subnumbers for the formulas
\startsubformulas
\placeformula[eq:2-a]
\startformula
\fakeformula
\stopformula
\placeformula[eq:2-b]
\startformula
\fakeformula
\stopformula
\stopsubformulas
It is clear that the equality (\in[eq:2-b]) is a consequence of (\in[eq:1]) and
(\in[eq:2-a]).
% To test how to change the number separator
\defineseparatorset[none][][]
\setupformulas[numberseparatorset=none]
\startsubformulas[eq:3]
\placeformula
\startformula
\fakeformula
\stopformula
\placeformula
\startformula
\fakeformula
\stopformula
\stopsubformulas
Prove relations (\in[eq:3]) using (\in[eq:1]).
\stoptext
%%%% end example
