where <TT>bbbb</TT> is the begin, <TT>eeee</TT> - the end of the block,
and <TT>xxxx</TT> is the execution address (init or run vector).<P>
The summary includes:<BR>
<TT>xxxx bytes</TT> - length of file, including headers<BR>
<TT>xxxx blocks</TT> - number of headers<BR>
<TT>xxxx inits</TT> - number of init blocks (<TT>02e2-02e3</TT>)<BR>
<TT>xxxx modules</TT> - number of <TT>FFFF</TT> headers (one at the beginning is required)<P>
All displayed numbers are hexadecimal, of course.<P>
You can redirect output to a file, for example:
