What platform? I'm not 100%, but on *nix writeln goes to stdout 
of the process and read* reads from stdin of the same process. 
The problem is that stdout is not connected stdin of the same 
process. In other words readf never gets past the "hello". Create 
two programs and connect them as such "writeProgram | 
readProgram".


p.s. next time, please post such to the learn subforum, thats 
properly a better place for this.
