Command: spoon

Name:
spoon - execute a parallel SLI-process
Synopsis:
Command spoon -> Child_PID %for parent process -> quit Command %for child process
Description:
Basic process management: execute a parallel SLI-process
Parameters:
In: Command (any): (However, Command is most likely to be a literal procedure...) Command will be executed by the child process, which will terminate after execution. It will be ignored by the parent process. Out: For parent process: Child_PID (integer): The child's process-ID. For child process: none.
Examples:
{ (I am the child!) = } spoon (I am the parent!) = Try this several times. You will notice the child message to appear before or after the parent message "by chance". (Even after the parent's I-prompt...)

Remarks:
A parallel process is forked. Parent and child will execute in parallel. There is no way to know which will start being executed first. Child inherits all open files, including stdin and stdout, from parent! If a SLI error is raised inside the child process, an error message is issued and the process is terminated, in oder not to leave two interactive SLI processes waiting for user input. A copy of the error message is printed to cerr, in case the standrad message stream M_OUT is redirected to a pipe (i.e. by the spawn command). Procedure: Call fork. Check if you are parent/child by test of (PID eq 0). If parent: discard (pop) Command, leave: (child)PID. If child : discard (pop) 0-PID, execute Command, quit.
