isCOBOL Evolve

WebClient integration with a web page

WebClient is Veryant’s solution to host desktop application in a web environment. Desktop applications will be rendered as HTML pages and will run unchanged in a browser.

Using WebClient a desktop application can be embedded inside a custom-built web page to provide additional functionality.

With the 2021R2 release, the range of capabilities have been greatly expanded.

isCOBOL applications can now interact with the underlying web page and the page can invoke isCOBOL code. Additionally, a new IWC-PANEL component has been implemented to host web components inside COBOL screen sections.

isCOBOL compiler

Starting from the isCOBOL 2021R2 release, the compiler option -sp, used to set the location of copy files, is not needed to include standard isCOBOL copy files.

The ANY LENGTH data item can now be used in LINKAGE SECTION items in the called program, even if the caller program passes a fixed length data item, allowing for more flexibility

New properties and syntax have been implemented to improve compatibility with MicroFocus and IBM COBOL dialects, easing the migration of code.

isCOBOL Runtime

In the 2021R2 release several new configuration settings have been added to allow unloading and reloading of classes to ease your application update process, and printing is now asynchronous, making your application more responsive for the end user.

isCOBOL EIS

isCOBOL Evolve EIS has been enhanced, and the HttpClient class that provides many useful features to communicate with existing Http Services like Web Services (SOAP / REST), now allows you to specify the Encoding charset when generating JSON content, and can now generate JSON data without the need for a top-level item.

The HttpHandler class, which provides a communication bridge between COBOL programs and HTML5/JavaScript pages using the HTTP protocol, can now accept JSON data without the need for a top-level item.
