It's the working name for new ZSQL methods which will work with positional 
parameters (preferably ? / qmarks) to provide more performance and 
flexibility for SQL statements. qmarks are preferred as the ODBC standard and 
using bound parameters allows the database to cache the statement even when 
the parameters vary. As a result it is less likely that the SQL statement 
becomes too long.
