! Remark:   i   --  Initializing 
!           x   --  This executable
!           p   --  Parent that spawned this program (ct)
!           c   --  Child process spawned by this program ms
!          _c   --  Communicate (Send & Rec) with child proc. 
!          _r   --  Receive
!          _s   --  Send
!          _g   --  Global var. 
!          _sp  --  Spawning util
