Hello World in Redcode

Here's the shortest "Hello, World!" program I could implement, written using the sts opcode which is available in exMARS Streams.

write   sts.a  hello,     0
        sts.b  }write,    0
        djn    write,     #7

hello   dat    72,        101
        dat    108,       108
        dat    111,       44
        dat    32,        87
        dat    111,       114
        dat    108,       100
        dat    33,        10
