Preface

jBC is a programming language that is used in jBASE post-relational (multi-value) DBMS. Syntax is Basic-like; compilation process firstly converts the source code to C which in turn is compiled for the target platform with the usage of standard C compiler.

For TAFJ it is converted to Java code rather than to C.

This is unofficial document; use it at your own risk - like TAFC :)) .. no, no joke - read its license agreement carefully.
