New Features in Enterprise Developer 4.0

Integration with Visual Studio

Back to Top

This release includes the following editor improvements:

• Inline rename refactoring - overwriting a variable name directly in the editor now invokes rename refactoring so you no longer need to select Refactor from the editor context menu.
• Extract to section - a new quick action (Visual Studio 2015 and later only) is available in the editor. It enables you to refactor your code by adding more sections in the code. This can help you create more entry points that you can use during unit testing.
• Automatic insertion of END-EXEC, END-TRY and END-PERFORM statements - the closing statements are now automatically inserted after you have typed the opening statements.
• IntelliSense filters (Visual Studio 2017 and later only) - when IntelliSense displays a list of suggestions, a number of icons at the bottom of the IntelliSense window now enable you to filter the suggestions.

Working with files:

• Copybook graphs - a context menu command, Show Copybook Graph, in Solution Explorer enables you to display the graphical representation of the copybook dependencies of COBOL programs.
• Open Folder mode (Visual Studio 2017 only) - support is now available for editing, compiling and debugging files opened in Solution Explorer in Open Folder mode without having to create projects.
• The file property pages now display a list of all Compiler directives that apply to the file.

New IDE configuration option:

• You can use the Limit IntelliSense Search Scope setting in Tools > Options > Text Editor > Micro Focus COBOL > Advanced that helps improve the editor performance.

Application Server JCA Support for Enterprise Server

Back to Top

This release includes the following enhancements:

• COBOL Resource Adapters now support WebSphere 9.0 and WebLogic 12.2.1.
• Tomcat 7.0 support for servlet generation with J2SEBeans.
• NullSearch utility - for COBOL resource adapters, this new utility provides assistance in locating NULL fields in mappings passed to Enterprise Server. When a large number of arguments is provided in the parameters passed to Enterprise Server, it is difficult to locate NULL fields, which are not allowed. The NullSearch utility isolates NULL fields, so the Java application can be corrected.

Build Tools for Windows

Back to Top

This release includes Enterprise Developer Build Tools for Windows, a separately-installable component of Enterprise Developer that has been designed to be used in environments where you want to work with your COBOL and PL/I projects but you don't want the overheads associated with the Visual Studio IDE.

Build Tools provide a lightweight, easy-to-install development environment that is well-suited for use in Docker containers and continuous integration or continuous delivery systems.

Code coverage

Back to Top

This release provides the following enhancements:

• In Visual Studio, the Micro Focus Code Coverage window now offers a File View in addition to the existing Program View.

Codeset support

Back to Top

Support has been added to enable codeset mapping to additionally be configured to use IBM's Conversion Tables directly instead of the Micro Focus supplied tables. You need to download IBM's conversion tables from IBM's Web site. Then you can use the MFCODESET environment variable to convert between IBM's CCSIDs.

Compiler directives

Back to Top

The following Compiler directives are new in this release:

• DISPSIGN - determines the display output of numeric fields with included signs, under an IBM mainframe dialect only.
• GNTLITLINKSTD - stops the suppression of call-convention 8 when both call-convention 2 and call-convention 8 are in effect for a .gnt file in an Intel x86 32-bit environment.
• ILSMARTANNOTATE - adds attributes to the items generated by ILSMARTLINKAGE, based on their data type, which can be used to identify the size or range of the item in COBOL.
• ILSMARTTRIM - trims any trailing spaces from a string item returned by the get property associated with an alphanumeric item processed by ILSMARTLINKAGE.
• MAINFRAME-FLOATING-POINT - specifies the format of a program's floating point data items: either IBM hexadecimal format or IEEE format. This directive is supported in managed code only.

The following Compiler directives contain new parameters in this release:

• CHECKDIV - a new parameter 'ACOS' now emulates a divide by zero operation on an ACOS mainframe system: the quotient and the remainder are set to the value of the dividend.
• OOCTRL - a new parameter, L, specifies whether to include directory location comments in .cls and .ins inheritance files.
• NUMPROC - a new parameter 'ACOS' provides partial compatibility with the behavior of NEC ACOS COBOL processing of invalid data in USAGE DISPLAY data items and invalid sign information in USAGE COMP-3 data items.

Data File Tools

Back to Top

It is now possible to export any filtered results. When filtering a data file, you can use the results to create a new data file - click Search > Export Results when a filter is applied to save the filtered records to a new file. You can:

• Save the filtered records to a new file.
• Save the records that match the specified filter (such as customer information or orders).
• Download a subset of the data from a remote file.
• Save a small portion of the data for testing purposes.

Debugging

Back to Top

This release includes the following enhancements:

• Enhanced .NET debugging in Visual Studio 2017 - a number of advanced debug features are now available when debugging .NET COBOL code. Features include support for performance tips, backwards debugging, an expression evaluator, integration with the Diagnostic Tools window, remote debugging of .NET COBOL applications, as well as support for IntelliSense in the debug windows (such as the Immediate, Watch, and QuickWatch windows).

• Debugging CICS channels and containers - you can now debug CICS COBOL applications that use channels and containers. The debugger now enables you to view the contents of any channels and containers, and to change content as you debug.

Docker

Back to Top

This release provides support to enable you to run your COBOL and PL/I applications in Docker containers, taking advantage of the many benefits offered by the Docker platform such as portability, performance, agility, isolation, and scalability.

Documentation on working with large applications

Back to Top

The product help now includes a new section, Working with a Large Code Base, that includes recommendations and best practices for working with large applications inside the IDE. It includes tips on how to structure your projects, how to optimize the performance of the IDEs, and step-by-step workflow showing how to move an existing legacy application into Enterprise Developer.

Enterprise Server

Back to Top

The following enhancements have been made to Enterprise Server:

• Conversation filtering - the Enterprise Server Communications Process (MFCS) can now restrict access to listeners by client address. You can specify any permitted or forbidden addresses either by IP address, network mask, or domain name, and use wildcards. Filters can be applied to individual listeners, communications processes, or to entire regions. More specific filter rules override any general ones.

• The Enterprise Server Security Facility now starts throttling Verify requests when it receives more than 100 requests per second.

  This can be used to limit the effectiveness of denial-of-service and brute force attacks. You can configure the value where throttling occurs. See Verify Request Throttling for more information.

• (Technology Preview only) Support for adding, deleting, and modifying XA resources in a live Enterprise Server region.

  It is now possible to add, edit, or delete XA resources while an enterprise server instance is running. Any changes made come into effect after any in-flight transactions have completed. The ability to make these changes in a live environment comes under the control of the existing enterprise server permissions.

• XA-compliant Resources (XARs) - this release provides enhanced CTF tracing that allows more flexible reporting of warnings and errors on the RM switch module level.

• A new Communications Server resource class - enables you to control the access to the Enterprise Server Console Log and Communications Server Log when external security is in effect for an enterprise server region; see Resource Classes for Communications Server for more information.

• Improved catalog availability - there is now an improved resilience to temporary communication issues with the catalog and error reporting enabling a region to stay active if a region has multiple catalogs defined and one of the catalogs is not available.

• Enhanced SSL/TLS certificate support - for communications with TLS (formerly SSL), additional certificate and key file formats are supported. Servers may now be configured with both an RSA and an ECC key and certificate.
• Enhanced SSL/TLS cipher configuration - for communications with TLS (formerly SSL), the permitted cipher suites and their preferred order can now be configured. The minimum size of Diffie-Hellman groups for DH key exchange can also be configured. The defaults have been made more secure.

Enterprise Server for .NET

Back to Top

This release provides the following enhancements:

• Limited support has been added for TLS (SSL) - you can now configure TN3270 and MFBINP listener channels for TLS (SSL). The seeout command-line utility and the JES public class API also now support TLS.
• Enterprise Developer for Visual Studio includes a new wizard that enables you to convert native MSS projects to managed MSS ones. The wizard is invoked using the Create Managed Mainframe Project context-menu command at project level in Solution Explorer.

File Handler

Back to Top

This release provides the following enhancements:

• The DFSORT and SYNCSORT emulations now support the NULLOFL parameter of the OUTFIL statement.
• The ASCIISOSI configuration option is now available. It adds the required SOSI characters to the relevant EBCDIC DBCS character strings in order for them to be displayed or written out correctly.

HCO for DB2 LUW

Back to Top

This release includes the following new features:

• Support for CHARSET EBCDIC COBOL stored procedures
• Seamless integration with DB2 LUW SBCS databases, providing various EBCDIC collation sequences
• 64-bit HCO command-line tools are now available across all supported platforms
• HCO DCLGEN enhancements that provide more copybook generation options

IMS support

Back to Top

This release introduces the following new features:

• The IMS Database Forward Recovery feature has been updated to provide point-in-time forward recovery that enables you to recover all database transactions completed up to a specified point in time, including date and time of day.
• IMS support now includes MFS code for Light Pen devices. In your MFS, include a DEV statement with the FEAT=PEN parameter, and set the ATTR property on appropriate fields to DET or IDET to make them detectable by a light pen. See your IBM documentation for details.
  Note: MFS that contains light pen code must be regenerated to take effect if the MFS is part of an Enterprise Developer project created using an earlier release.
• Support for export and import of IMS-configured enterprise server regions through Server Explorer.

JCL support

Back to Top

This release introduces the following new features and enhancements:

• Micro Focus FTP utility - you can now configure MFFTP to not process trailing blank spaces for a GET command, by setting the new control variable MFFTP_PROCESS_TRAILS_ONGET=FALSE and setting the LOCSTAT value TRAILINGBLANKS=FALSE.
• A new API has been introduced - MVSSPLPB - that enables you to search all job information held in the JES spool control files. It is more comprehensive that the existing MVSCASPB API, and should instead be used for all new spool enquiries.
• A number of new environment variables have been introduced that enable you to configure the JES startup behavior with regards to opening user catalog files. You can configure JES to open user catalog files only when they are required (and not during system startup), and you can configure JES to retry opening a catalog file that has failed to open. These changes increase the resilience of the JES system, as you can mitigate against JES startup failures if the user catalog files are not readily available whilst the region starts. See Configuring Multiple Catalogs for more information.
• The public catalog API, MVSCATPB, has been enhanced to better report on file errors when opening catalog files. The following new functions have been added to mfpubcat.cpy: GCFS, GNFS, STNI, GCFE, and GNFE. See Functions for more information.

Library routines

Back to Top

The following library routines contain new functionality:

• CBL_GET_OS_INFO - this library routine can now detect if the program is running within a Docker container: cblte-osi-rts-capabilities parameter, bit 7.

Mainframe Access

Back to Top

The installation process has been changed as follows:

• A single installer for both Mainframe Access and the Mainframe Access z/Server support is provided.
• There is now only one XML configuration file for Mainframe Access. There is also a new configuration utility that guides you through the configuration process.
• Specify your own JES console character - it is now possible to configure the Mainframe Access installation to use a different JES console character instead of the default ("$"). To achieve this, use the new JES_CONCHAR configuration parameter.

Enhancements are available in the following areas:

• The Mainframe Call Generator now runs in an independent address space. Previously, it was possible for code run in the MFA address space to enter a supervisor state. MCGLIB is now the new address space's STEPLIB. This enables other user modules to be called without placing them in MFA's STEPLIB, as was previously necessary. See Mainframe Call Generator: Calling Programs on the Mainframe for more information.

Micro Focus Unit Test Framework

Back to Top

This release provides support for the following functionality:

• Generation of unit test stubs for selected entry points within your program.
• Support has been added to Visual Studio for unit testing of managed procedural projects.

OpenESQL

Back to Top

This release provides the following new features:

• Support for SQL Server 2017.
• The SQL(TRANSACTION) compiler directive has been enhanced to clearly define transaction boundaries.
• A new SQL(NOWHERECURRENT) compiler directive that allows you to define updateable cursors that do not do positioned updates or deletes with PostgreSQL or MySQL.
• Larger communication area (PID) that accommodates longer plan and program names.
• SQL(OPTIMIZECURSORS) has been enhanced for consistent and better cursor performance across all OpenESQL backends.

Platform support

Back to Top

Note the following changes in platform support for this release:

• Windows 8 and Windows Server 2012 are no longer supported for developing applications. They are still supported for deployment.

PL/I support

Back to Top

PL/I compiler and Run-Time System enhancements:

• Support for the following built-in functions - CHARVAL(), COMPARE(), CURRENTSIZE(), EDIT(), PICSPEC(), SOURCEFILE() and SOURCELINE().
• Support for additional DATETIME() format strings.
• Support for the FLUSH FILE(*), ITERATE, and RESIGNAL statement.
• Support for the XMLOMIT and XMOLATTR attributes on variable declarations.
• Support for the MARGINI compiler option.
• Support for the SIZE and STRINGSIZE prefix conditions.
• Improved support for the repeat factor on arrays of AREA variables.
• Improved pointer arithmetic on 64-bit platforms.
• Where necessary, MFPLX now recognizes selected *PROCESS statements and passes them to the appropriate preprocessors.

PL/I macro preprocessor:

• The Micro Focus macro preprocessor now provides a new default behavior that mimics IBM's RESCAN(ASIS) behavior. In addition, a new option, rescan_upper, has been introduced to enable you to optionally mimic IBM's RESCAN(UPPER) behavior.

Improvements in compatibility with IBM's Macro Preprocessor:

• Allows OTHER as an acceptable abbreviation for OTHERWISE on a macro SELECT statement.
• Supports the SCAN/NOSCAN option on declaration of macro variables.
• Implements the NOSCAN option on ANSWER statements.
• The %NOTE message format has been modified to match IBM's behavior.
• The SYSVERSION built-in function has been modified to always return a value of 22 bytes in length (space padded, if necessary).
• Relaxed diagnostics for scenarios where Enterprise Developer is generating a warning message and IBM does not.

(Technical Preview) Interaction with COBOL AMODE and 370 Assembler programs (Windows 32-bit only):

• A new compiler option is available which enables Open PL/I to interact with 370 Assembler, and with COBOL programs compiled with AMODE. See the product help for the current limitations to this support.

Web service clients

Back to Top

This release provides the following enhancements for Web service clients:

• Improved support for larger, more-complex WSDL files, including:
  • Configurable generation of variable arrays and repeated structures by specifying the Inline-Array-Size-Limit parameter.
  • Generation selection for service, port, and one or more operations.
• Support for SOAP version 1.2 in addition to version 1.1.

XML Extensions

Back to Top

Two new state management statements have been introduced, XML GET WHITESPACE-FLAGS and XML SET WHITESPACE-FLAGS, that enable you to control how whitespace is handled when importing data; refer to the topic Handling spaces and whitespace in XML for more information.
