The first step is planning. Always.

What do you want it to achieve? What are the input arguments? What are the output arguments? What kind of routine?

Hi,
You can go through the in-built routines first and understand what is the purpose of the routines and what is the Syntax.

Then you can start creating simple routines does some date or string manipulations.

No!!!

You start by producing a written specification. Always.
