function send

 ; copies from R(1000), 5*4 bytes i.e. 5 integer registers, into the

 ; date field of the block structure

 move_bytes(r(1000), block.data, 5*4)

 

 ; send the block structure on channel 190 (channels 190 to 199 available).

 ; return gives diagnostic information

  return = bcc_send(190, block)
