Not really sure what you want to accomplish, but ...
(A) if child.program could take a variable then this should do it ...
    message="hello world"
    ./child.program "$message"
(B) or parent.program could set a environmental variable (line 1) and 
child program could print it (line2) ...
    (line 1) export MESSAGE_1="Hello world"
    (line 2) echo "$MESSAGE_1"

... does any of that help?
