[tex-eplain] indexing appendices

[Helmut Jarausch]

Hi,

I have a document which consists of a main part and several appendices
named A, D, ...

Page numbering for the main part as well as for each appendix starts at
page 1.  I'd like to create an index which shows the plain page numbers
for the main part (only) and page numbers prefixed by a letter for the
corresponding appendix, something like

loop   7, A2
condition  A2, D5

Is this possible with Eplain?

Many thanks for a hint,

Helmut Jarausch
