I made a basic remote program that I found very useful, basically you place a PC and then send it the code it must execute with a code/key to verify that this computer must run it
CLIENT STARTUP FILE:
local keyword="1234"
rednet.open(whateversideyourmodemison)
while true do
local id,msg,dist=rednet.receive()
temp=textutils.unserialize(msg)
if type(temp)=="table" and temp[1]==keyword then
loadstring(temp[2])()
end
end
HOW TO SEND DATA:
basically you make the code (eg: 'turtle.up() turtle.place() turtle.down()') in string form - THIS IS IMPORTANT, MUST BE A STRING OR WON'T SERIALIZE
then you make the keyword(eg: '1234')
put them into a table like so
mytable={}
mytable[1]="1234"
mytable[2]="turtle.up() turtle.place() turtle.down()"
and then send it in serialized form
rednet.open(modemside)
rednet.broadcast(textutils.serialize(mytable))
this can be summarized into 2 lines
rednet.open(modemside)
rednet.broadcast(textutils.serialize({keyword,code}))
so you no longer have to store any programs on your computers, you just send them their tasks from the host computer, you can even tell them to send the output back etc etc
