Introduction to jBASE/TAFC data files
The most widely used formats for data files nowadays are "J4" and "JR". The former has size limitation (up to 2Gb if OS-level limits allow that) and needs resizing on regular basis though when it's properly sized it's faster. "JR" - "resilient" - doesn't have size limitation and doesn't need resizing.
The following examples serve as a brief introduction to jBASE data storage. They can be executed in jshell prompt or (except JED - it makes no sense) in a jBC program or subroutine (using EXECUTE/PERFORM).
