Answer 1

Its Called a "Bincond" Operator

Statements Like:

(Price > 75 ? 'High':'Low')  

are also valid

For Handling Null Records:

((Name is null or IsEmpty(Name)) ? {('unknown')} : Name)

Use them in a foreach statement with alias along other fields i.e:

A = load 'x/y/Price.csv' as (Name, Product, Price);
B = foreach A generate Name, Product, Price, (Price > 75 ? 'High':'Low') as Indicator;

dump B;
