rednet.send(id,msg) is an computercraft API, not program. Use edit filename for programing (or text editors and copy program to mods/computecraft/lua/rom/programs)

Like a >edit helloworld (opening in-game editor)

term.clear

print('hello world')

rednet.send(4,'hey you')

[ctrl] - save, [ctrl] - exit (menu of edit program)

helloworld (running program)
