Re: DLYJOb in Perl

Thanks Blair . That is exactly what I was looking for , a true wait and not
some kind of a resource sensitive looping.

I've not done Perl on the AS/400, but the general Perl function is
'sleep(n)' where n is the number of seconds to sleep.  IIRC, the AIX
implementation does this with a signal, so it's a true wait and not some
sort of CPU-intensive polling loop.  There's also 'alarm', but the
perldoc advises not to mix sleep and alarm.

The perldoc also advises that to sleep less at a finer granularity than
one second, it's possible to use the syscall 'setitimer', but I doubt
that the AS/400 Perl is so endowed.
