where ''n'' is a variable or value known at compile time.
 
 
 
== Semantics ==
 
 
 
This will limit execution of a block to a certain process whose rank is guaranteed to be that specified.<br><br>
 
''Note:'' A variable declared within a proc block and allocated multiple will in fact, by inference, be allocated to the group of processes which contains a single process who's rank is the same as the proc block's.
 
 
 
== Example ==
 
 
 
#include <io>
 
function void main() {
 
    proc 0 {
 
      print("Hello from 0\n");
 
    };
 
 
    proc 1 {
 
      print("hello from 1\n");
 
    };
 
};
 
 
 
The code example will run on two processes, the first will display the message ''Hello from 0'', whilst the second will output the message ''hello from 1''.
