| On October 7 2015, Build 64 of the Janus/TN3270 Debugger Client was released.
| | ''' |
| | |
| Build 64 contains improvements and fixes for the Debugger Client IE Mode settings of mergedPac or NewPac which are used with a Microsoft IE browser.
| |

| ==Janus/TN3270 Debugger Build 63 with Model 204 Version 7.6==
| |
| <div class="mw-collapsible-content">
| |
| On July 6 2015, Build 63 of the Janus/TN3270 Debugger Client was released.
| |
| | |
| Build 63 contains support for <code>HTTP:</code> style URLs for PAC (Proxy Auto Config) files, for sites
| |
| using a Debugger Client <b>IE Mode</b> setting of <b>mergedPac</b> or <b>NewPac</b> with a Microsoft IE browser. Previously, only <code>FILE:</code> style URLs were supported for PAC files.
| |
| | |
| When Build 63 is used with Model 204 version 7.6, two additional features are available:
| |
| * Run Until, White List, and Black List processing is now done for procedures on daemon threads as well as for those on the master thread.
| |
| * The Expand Object feature supports the JSON system object type, which was added for Model 204 7.6.

| |
| <div class="mw-collapsible-content">
| |
| | |
| Version 7.5 of Model 204 (December, 2014) follows the acquisition of the Sirius Software product line and integrates the Sirius and Janus software products into the Model 204 nucleus. One of the more exciting results of the integration is Simple Objective User Language, or SOUL. SOUL adds object-oriented programming to, and replaces the name of, User Language. It comes with no additional cost, and it is backward compatible with existing User Language applications.

| ===Release notes=== | |
| The main features in this release of Model 204 are summarized on this page and described in greater detail in the [[Release notes for Model 204 version 7.5|version 7.5 release notes]].
| |
| | |
| ===SOUL===
| |
| Here are some of the new SOUL features:
| |
| <ul>
| |
| <li>Mixed case User Language support
| |
| <li>Generic User Language sorting, searching, and subsetting facilities
| |
| <li>Improved syntax for setting/retrieving large object (LOB) values (directly to/from longstrings)
| |
| <li>Enhanced printing and auditing statements
| |
| <li>Implicit concatenation
| |
| <li>The Assert and Loop Next statements
| |
| <li>A macro language
| |
| <li>Data types:
| |
| <ul>
| |
| <li>Longstring (including image string items > 255 bytes)
| |
| <li>Unicode
| |
| </ul>
| |
| <li>Full OO programming capabilities including:
| |
| <ul>
| |
| <li>Class and object definitions, methods, public/private class variables, inheritance, polymorphism, etc.
| |
| <li>Support for exceptions such as Try, Catch, and Throw statements
| |
| <li>Support for named parameters
| |
| <li>Support for method variables, that is, variables that can be used to dynamically invoke functions or subroutines
| |
| </ul>
| |
| <li>Shorthand right-side assignment operators:
| |
| <ul>
| |
| <li>%a = @ + 1
| |
| <li>%a = @ * 1
| |
| <li>%a = @ / 1
| |
| <li>%a = @ :div(1)
| |
| </ul>
| |
| </ul>

| <p class="note"><b>Note:</b>
| |
| These features were formerly part of the <var class="product">Janus SOAP</var> product. In version 7.5 of Model 204, these features were incorporated into <var class="product">Model 204</var> such that <var class="product">SOUL</var> applications continue to work as they always have. <var class="product">Janus SOAP</var> remains as an add-on product that provides support for [[Janus SOAP|XML processing]]. </p>

| | |
| ===64-bit enablement of the Model 204 infrastructure===
| |
| Model 204 moves “Above the Bar” to increase scalability, performance, and growth potential. With this release of Model 204, 64-bit addressing becomes the de-facto standard for all subsequent versions. This might bring new challenges to customers who have written assembler language functions for use within Model 204, and Rocket Software has prepared a new set of service offerings to help accommodate upgrade and conversion needs.
| |
| | |
| ===Physical field groups===
| |
| Model 204 supports non-relational, denormalized data structures, and its efficient processing of multiply-occurring fields provides significant cost and performance benefits. This processing is enhanced by the availability of physical field groups, which let you view and process groups of fields as logical entities.
| |
| | |
| ===Range searching by Ordered Index (OI) chunk===
| |
| The new CHUNK attribute of the DEFINE FIELD command offers significantly more efficient searching on Ordered Index numeric (ORDERED NUMERIC) field ranges. The storage for the file's values of these fields is automatically maintained, divided into ordered sub-ranges ("OI chunks") whose interval-size is part of the CHUNK definition. Finds of value ranges of these fields search by OI chunk rather than by individual value, so they entail fewer scans of the Ordered Index entries.
| |
| | |
| ===Expanded file-record limit===
| |
| In version 7.5 of Model 204, the record limit per file increases from sixteen million records to forty-eight million records.
| |
| | |
| ===New debugging tools===
| |
| Developing web and screen applications that use Model 204 is made easier by newly acquired debuggers: <var class="product">Janus Debugger</var>, <var class="product">TN3270 Debugger</var>, and <var class="product">SoftSpy</var>.
