Again a similar thing in php - I look for a certain string in the output and
use that as a return code
$udtCmd="LANG=en_US.UTF-8;export LANGcd
/usr/ud/accounts/$account;/usr/ud71/bin/udt RUN $BP $prog";
$result = array();
exec( $udtCmd, &$result);
foreach ( $result as $v )
{
if (substr($v,0,6)=="!stat="){
$stat=substr($v,6,10);
}
}

Subject: Re: [U2] Setting return code when a Universe process terminates
We do something similar here. In a UNIX shell script we call a Unidata
sub and capture the output into a log file.
echo Running BP $udtProgram >> $logfilepath
$UDTBIN/udt<<EOD | tee -a $logfilepath
RUN BP $udtProgram -N
bye
EOD
Any output from the Unibasic program will be captured. In this case we
send it to the log and to standard output. If you could limit the output
of the Unibasic sub to only the values, or messages you wanted, you could
use DISPLAY to return them. A more experienced *nix person might be able
to tell you how to pipe the output to a variable, or possibly your perl
program could use the standard ouput of the shell program.
Hope this helps.

Subject: Re: [U2] Setting return code when a Universe process
terminates
Ian, I tried for a long time to figure out a way to do this entirely from
within UD. Couldn't figure it out. I hit two walls. First, the exit code
that nix receives is the status of the udt command. If you're program runs
at all, you get a '0'. The second wall was when I tried setting an
environment variable from within my code. The issue there is that shelling
out starts a new shell that is closed as soon as you return to UD. The
only way I could make it work was to echo a status code to an ascii file.
I ended up using a shell script to call my UniBasic program and pass in a
location and name of an ascii file. The program determines exit status and
echoes it to the ascii file. After the program completes, the shell script
checks the contents of the ascii file and does an 'exit #'. I've had this
working for a couple years with no issues. I'd be willing to discuss
details off-list if you like.
