Are you sure? I though it was 0x501... and the Helpreply was 0x502 (or is
my memory failing me again?!)

An easy test to do is to put a debugging 'printf' into your message handler
and print out the recieved message numbers... I use

bbc_vdu(26); bbc_vdu(4); /* get the cursor in VDU4 mode at top left of scren*/
printf("Message number: %x", blah);

or you could just use the printf, and redirect your programs output to
a file
(in !Run, change
  Run <Obey$Dir>.blah
to
  Run <Obey$Dir>.blah > <Obey$Dir>.output
)

This way, you'll know *what* messages you're actually recieving, which is
always a good place to start working out why nothing's happening...
