When the delay is important, I start a new process that dies after the job is 
done. I don't like a quite always sleeping but always here process. A cron can 
do that too. 

if (jobTime($i))
create process (...)
end if

Re: What's the Longest you can DELAY PROCESS?

2017-10-16 Thread Chip Scheide via 4D_Tech 
have a "cron" utility
a process that has a list (records, array, whatever) of all processes 
that are deamons
have it wake the deamon as appropriate using Call process.

All deamons use Pause Process, rather then delay to sleep.


ex:
Cron:

Repeat
Process count := number of processes to manage

 for($i;Process count)
   
  if (time_to_wake_process($i))
   call process (Deamon_Process_IDs{$i}
  end if  
 end for 
 delay process current process, 1 minute, or whatever)
until(Quit4D)

Thanks Jim,

It sounds like it almost has to be an integer value...
If there is a limit, it would be nice for the docs to specify what the limit is.

Max delay used to be something like 32000 ticks.  (We have an old //comment
from 2006 that thinks so anyway)
