its not part of Ada as I recall. it was vendor specific if they had it at all...
its not there in cobol (afaik)
PL/I didn't have it...
many languages don't have it.
but anyway here is a potentially good reason why the database doesn't do it....
system would run with the permissions of the process in the OS. consider what system( 'rm -rf $ORACLE_HOME' ); might do since the processes run as oracle....
I'd hate that.
In 8.0 and up, you have extprocs. extprocs run with the privs of the user who starts the LISTENER (not the database). This is good since you can start the listener for the extproc service as some other NON oracle user (eg: user=nobody or something).
If you would like, i could send you the system command as an extproc for 8.0 and up.
