Natural-ADABAS to JAVA-Oracle-UNIX program conversion

This will be the first of many simle and advanced JavaCC and jjTree examples

Transaction processing, flow control by using threads to enable online programs
to use maps, field value transfer from maps to the transaction program and vice versa.

Let's begin with some very simple JavaCC examples:
