Thanks for the various replies.  I now have the ultimate Hello World program
with the obvious bug in the first one where I didn't have the text right!
(Using cut & paste from example code) Doh.

$CONTROL USLINIT
BEGIN
  INTRINSIC PRINT;
   BYTE ARRAY OUT(0:12);
   PRINT(OUT, -MOVE OUT:="Hello World!", 0);
END.

I don't get the warning on the PRINT now.

I don't understand why it expects a word array when the documentation -

http://docs.hp.com/en/32650-90821/ch04s177.html

says it's a "character array".  Isn't that a byte array?

Cheers

Peter
