jbase Query Language Sentence Construction

A jQL Command sentence must contain at least a Command and a File name. The Command specifies which process to perform and the filename indicates the initial data source.
You can add optional clauses to refine the basic Command. You can use clauses to control the range of eligible record keys, define selection and sorting criteria, or to specify the format of the output, and so on.
REMEMBER: only a verb and filename are required. The following list summarizes each element in the Syntax.
