One way to solve your problem is to create a multiplexor. As the name implied,
the multiplexor will "ALT"ternate between two or more input screen channels 
and writes the output to the "real" screen channel one at a time. This 
prevents processes from overriding data to the screen channel.

You can write the multiplexor using the ALT construct,such as,

   SEQ
     WHILE continue
       PRI ALT
         quit ? any
           SEQ
             continue :=FALSE
         ALT i=0 FOR n
           ... process input screen channels

Or you could use the scrstream.multiplexor PROC from INMOS-TDS by including:
"#USE interf" statement in your occam program.
