The following definition:
\def\holindexon{\def\holin...@aux##1{%
\suppr...@quotechars
\MMM{\def\${\noexpand\$}
\edef\Temp{##1}\index{\Temp }}}}
The last line of which I changed to:
\edef\Temp{##1}\index{!\Temp }}}}
I did this in a file called rbj.sty, which is as follows:
\typeout{$Id: rbj.sty,v 1.2 2010-08-08 15:50:44 rbj Exp $}
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{rbj}
\RequirePackage{ProofPower}
\RequirePackage{mathabx}
\def\Zdef{\MMM{\corresponds}}
\def\holindexon{\def\holin...@aux##1{%
\suppr...@quotechars
\MMM{\def\${\noexpand\$}
\edef\Temp{##1}\index{!\Temp }}}}
I then invoked package rbj instead of ProoFPower in my
ProofPower .doc file.

Unfortunately the distinction between tex and Latex
environments is one which I have not grasped, so I don't
know which I am in. However, since ProofPower uses \def I
guess it must be in a tex environment, and so I would
suppose that my change is also.
Possibly my problem is that my redefinition comes later than
the crucial invocation of HOLindexOn.
I see that it is invoked immediately, so perhaps I should
reinvoke after my redefinition.
