HSDL - Default Value - Use a expression - Sample Groovy expressions

Summary

Need a sample to create my own expression for defaulting values in HSDL fields

Hi,

I'm trying to default Job Code based on assignment number after it is entered in HSDL spreadsheet. My sheet has only attributes from assignments. While updating an assignment when some assignment number is entered it must default Job Code attribute. There is an option like 'use an expression' in which we are supposed to use groovy expressions. So I searched for some sample expressions in seeded ones. I was not able to find. Can someone please help me in this?

Thanks & Regards,
