Thanks for that.

The Automator suggestion works just like trying to call the shell command f=
rom an Applescript--I think it's pretty much the same thing; the app seems =
to run, delaying for the total of several delay commands, but does not emit=
 any sound.

However, my "Beep" function uses Character'val(7), the ASCII bell--macOS no=
rmally interprets this to play the default system sound which for some reas=
on is not making it to my speakers when run from Automator/Applescript but =
does work when run from terminal. But I have a function called Execute_Shel=
l() which binds to the =EF=BB=BFC command like this: pragma Import(C, syste=
m). Then if I put

say hello

as the command string for Execute_Shell and drop it into the Automator work=
flow as described in your link, it _does_ work correctly. Applescript proba=
bly gets the same result.

The Alfred method looks interesting but I'm not going to try it out right n=
ow.

The method using the line

/usr/bin/automator /path/to/the/file.workflow

Also works the same--"say" works but not playing ASCII bell. However, it re=
quires launching from a terminal.

Sort-of-bottom-line: Calling the Ada executable in Applescript or Automator=
 without invoking a terminal will allow "say" and probably "afplay" to work=
 but not ASCII bell . ASCII bell works when executing Ada from a terminal a=
nd also "say" and probably "afplay".
