Hi Norman,
Here is a example of multiprocessing with custom IPC in REBOL :
1- Save these two following source files in the same directory
2- Open a REBOL console, change-dir to the directory and do %calc-client.r
3- Watch what happens...
HTH,

--- file: calc-client.r ---
REBOL [
Name "Client"
File: "calc-client.r"
Comment: "Process launching a task and waiting for completion (acting as client)"
]
launch "calc-server.r" ; Create a new REBOL process
server: open tcp://localhost:1234
print "Waiting..."
wait server ; wait until other process finished his job
result: copy server
close server
print ["Calculation finished, result =" result]

serve: open tcp://:1234
client: first serve ; wait for other process to connect
result: simulate-calc 0:0:10 ; ten second calculation
insert client mold result
