You need to generate "connect" messages, whose syntax is as follows: 

"connect obj_A outlet_A obj_B inlet_B"

obj_A, outlet_A, obj_B, inlet_B are all numbers. 

The meaning of outlet_A and inlet_B should be clear, but note, that
in/outlets are numbered starting with 0. 

obj_A and obj_B also are numbers, they are given according to creation
order. So basically you need to keep track of these numbers yourself.
The object that was created first gets the number "0", the second is
number "1", the third gets a "2" and so on. 

If you created these objects using dynamic messages: 

obj 10 0 metro 100
obj 10 25 random 200

then this message will connect the metro to the random as you would
usually do by hand: 

connect 0 0 1 0

The metro is obj_A==0, the random is obj_B==1, and we use both outlet
and inlet 0, that is, the first.

If you then create another object, say a sender: 

obj 10 50 send randoms

You can connect the "random" to the "send" using: 

connect 1 0 2 0

Now guess, what adding this will do: 

obj 0 0 tgl
connect 3 0 0 0

Attached is an example.

Ciao
