Hand shake between Variables

[tnewbie]

Hello Talend Experts,

Suppose I have a complex logic that i want to handle in multiple steps, instead of trying to achieve everything in one step. Can i achieve this with variables as shown in the below image, and what will be the hand shake between variables and what will be the input/output hand shake between them 

 Var 4 will be the final output

The tMap variables are fired strictly in order (top to bottom) for each row of data brought in via the Main flow. They hold their values between rows as well. This tutorial goes through this functionality in a bit more detail....
