I'm trying to make my PC termianl read the From header
for a new incoming mail.
After reading the sources in /acme/mail/src, I made small
changes to the function Box.readmore() in box.l like as:
in while() loop to read new comming mails,
new = true;
say(buf); <----added line
and
defined say() in the box.l file like
void
say(byte *msg)
{
rfork(RFENVG|RFFDG|RFNOTEG|RFMEM);
execl("/bin/pub/say", "-l /dev/audio -C 2", "New mail arrived
from ", msg);
}
After above change, (I really don't know whether the flags
for rfork() are approapriate) the rsynth program reads and
speaks! the "From" and "Subject" line when a new mail arrived
to me.
However, after that, the Mail program goes into mad, and I
cann't end the session clearly.
Then, I searched the on-line manuals, and found something
notices for exec() in Alef environment, saying exec() may be
called only from the mail task....
If I want to fork/exec a new program like the present case,
can I do it otherwise?

surely you want to fork a new process for the say rather than overwriting
the old one?
i haven't looked at the source, but perhaps invoking
proc say(buf);
might serve you better?
