Actually, the calling conventions for SAPI 4 are somewhat different.  And a
change Microsoft made a few months ago which disables JavaScript's ability
to call SAPI 4 implies that there are some bugs in SAPI 4 which Microsoft
doesn't plan to fix.  Remember that SAPI 5 has been out for 5 or 6 years,
and SAPI 4 is older.  

I was going to paste into this message the code of a PowerBasic program
which uses the first available SAPI 4 engine to speak whatever is on the
command line.  It can be called from batch files or CMD files.  The
executable is on my web site.  I think this is one of the programs that got
Jamal started on Windows programming.  It is derived from another PB program
written by one of PowerBasic's staffers for the console version of their
compiler.  But the source is on a different machine, and this will have to
wait for another night.
