Dear all,
A few days ago (10 April 2013, Vol.106, Issue 25) I posted a question about giving related but not necessarily adjacent floats the same number, as for example Fig. 2a and Fig. 2b.
In the meantime I found a, not very elegant, solution that only partly satisfies me.
Here is a working example: (I trust the cow and the mill can be found).
 %---------------------------------------------------
\useexternalfigure[SmallCow][cow.pdf][height=2cm] 
\useexternalfigure[MediumCow][cow.pdf][height=3cm] 
\useexternalfigure[Mill][mill.png][height=3cm] 
\definelist[figure]
\setuplist[figure][prefix=yes,label=yes,alternative=c]

\starttext
This file is for testing the possibility of giving two related musical examples (in old and modern notation respectively) the same figure number with a. and b. as suffixes to the number proper. 

\placefigure[here][SmallCow1]{A small cow.}
{\externalfigure[SmallCow]}  

A cow again, in two sizes.

\in{Figure}[SmallCow2]a shows the same cow as \in{Figure}[SmallCow1]. 
\placefigure[here][SmallCow2]{{\bf a}. Another small cow.}
{\externalfigure[SmallCow]} 
And here a larger cow (\in{Figure}[MediumCow1]b).

\setnumber[figure][1]
\placefigure[here][MediumCow1]{{\bf b}. A larger  cow.}
{\externalfigure[MediumCow]} 

And here comes a mill.
\placefigure[here][Mill1]{A mill.}
{\externalfigure[Mill]}  

\page
{\bf List of Figures}
\placelist[figure]
\completecontent
\stoptext 

%----------------------------------------------------
This way "a" and "b" become part of the caption text, resulting in: Figure 2     a  A small ….. etc., and: Figure 2     b  A larger …etc. Likewise in the List of Figures. This is not what I would like.

Is there a possibility, when not using Combinations, to get: Figure 2a    A small …..  etc?

Wherever possible I use Combinations but in some cases examples to be combined are very different in size and shape and/or too large to fit on one page together, so that one of them gets cut off.
Is there a possibility, when using a combination of figures, to split it, in other words, to separate the figures spatially, to allow them to appear on consecutive pages, and maybe even allowing some text in between?

Thanks in advance.

Best regards, 

Robert Blackstone
