Substring values

Hi Experts,

I am having a field value Ex: Empid : IP1234567890 THOMAS PHILIPS MARK

How can i achieve from IP1234567890 separate and name separate THOMAS PHILIPS MARK

For Empid i have given as substring properties starting 1 to 12 but for last name how can i give the values in substring because the name will be dynamically changes based on employee name so how can i add the count in substring.

Regards,

Shaik
