Thanks very much for your assistance. Unfortunately your test file 
when processed by texexec blows up in a manner similar to eplain.tex. 

! Undefined control sequence.
\uncatcodespecials ... `##1 = \other }\dospecials

\idx at getverbatimarg ...ingroup \uncatcodespecials
                                                  \catcode \idxargopen

l.11 \idx{

There is an inherent incompatiblity between eplain.tex and Context 
that I cannot conquer.  Yet Context badly needs the greater indexing 
power of makeindex and eplain or its equivalent.

My workaround has been to create my own crude indexing macro and 
\write procedure. Some hand editing of the output book.idx file is 
still needed before processing through makeindex. But at least it 
doesn't blow up. 
Here is my kludge:
The resulting book.idx file has statements of the form 
...which requires a mass change from \\indexentry  to \indexentry.
