Re^2: Yet another spawn question. Portable method?

My apologies for the missing question - updated.

As for the chain, each time a script is started, an integer is passed as an arg that indicates how many times the script can be spawned. Each spawn decrements the int. "perl spawn.pl 3" will cause 3 instances of the script to be spawned:

D:\Views Tests>perl spawn.pl 3
Starting PID 3616 as instance 3
Starting PID 5940 as instance 2
Starting PID 6064 as instance 1
PID 3616 ended

D:\Views Tests>Starting PID 4564 as instance 0
PID 5940 ended
PID 6064 ended
PID 4564 ended

> Each spawn decrements the int. Still, you are unnecessarily giving up control, like the possibility to kill the master and all children at the same time. see also `perlipc` This is not my field of expertise, but IMHO your requirement not to use extra modules will make this a rather complicated task.
