    <p>I just looked at the NACA page and docs. From their documentation:</p> <p><em>"The generated java uses a Cobol-like syntax. It's as close as possible from original Cobol syntax, within of course the limits of the Java language. Generated code doesn't look like classical native java and is not object oriented from the application point of view. This is a by design strong choice, to enable a smooth migration of Cobol developers to the Java environment. The goal is to keep business knowledge in the hand of people who wrote the original Cobol programs."</em></p> <p>I didn't see an example, but the quote gives a strong flavor of the result. Its COBOL coded in Java.</p> <p>You can always build a "Translator" from one language to another, by simply coding an interpreter in the target langauge. That's IMHO an absolutely terrible way to translate a langauge as you end up with the worst of both worlds: you don't get the value of the new language, and you still have to have knowledge of the old one to keep the result alive. (No wonder this thing is called a "Transcoder"; I'd never heard this term before).</p> <p>The argument for this stunt is to dump the costs of the mainframe. Where's the evidence that the costs of working on the converted program don't swamp the savings? I suspect the truth is that the operations people lowered their cost by dumping the mainframe, and they couldn't care less that the maintenance tasks got more expensive. While that may be rational for the operations guys, its a stupid choice for the orgnization as a whole.</p> <p>Heaven help people that are a victim of this tool.</p> <p>EDIT May 2010: I found an example of NACA's output; one of <em>their</em> testcases. This is absolutely magnificent JOBOL. Its a good thing they are <em>keeping</em> their COBOL programmers and don't want to hire any Java programmers. As your read this, be sure you remember this is <em>Java</em> code.</p> <pre><code>/* * NacaRTTests - Naca Tests for NacaRT support. * * Copyright (c) 2005, 2006, 2007, 2008 Publicitas SA. * Licensed under GPL (GPL-LICENSE.txt) license. */ import idea.onlinePrgEnv.OnlineProgram; import nacaLib.varEx.*; public class TestLong extends OnlineProgram { DataSection WorkingStorage = declare.workingStorageSection(); Var W3 = declare.level(1).occurs(10).var(); Var V9Comp010 = declare.level(5).pic9(10).var(); Var V9Comp014V4 = declare.level(5).pic9(14, 4).var(); Var VX10 = declare.level(5).picX(10).var(); public void procedureDivision() { setAssertActive(true); move("9876543210", VX10); assertIfDifferent("9876543210", VX10); move(VX10, V9Comp010); long l = V9Comp010.getLong(); assertIfFalse(l == 9876543210L); multiply(1000, V9Comp010).to(V9Comp014V4); assertIfFalse(9876543210000L == V9Comp014V4.getLong()); String cs = V9Comp010.toString(); cs = V9Comp014V4.toString(); assertIfDifferent("9876543210000.0000", V9Comp014V4); inc(V9Comp010); assertIfFalse(9876543211L == V9Comp010.getLong()); CESM.returnTrans(); } </code></pre> <p>Kids: This is only done by professionals.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
