View source for Proc

== Syntax ==

proc n<br>
{<br>
process body<br>
}

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>
 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''.
