Syntax

{
process body
}
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.
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.
Since: Version 0.41b
