We supply a number of demonstration programs to help you better understand some of the concepts involved when working with
COBOL projects in Visual Studio.
The demonstration programs are installed in subfolders under
%PUBLIC%\Documents\Micro Focus\Visual COBOL\Samples by default.
You can access the demonstrations with the help of the
Visual COBOL Samples Browser for distributed application samples. See
To start the Samples Browser for access instructions.
The following categories of demonstrations of native code are available:
- CGI
-
- Simple CGI application
- Demonstrates how to use native COBOL to create CGI programs which accept data from a form on a Web page and then redisplay
that data in another Web page.
- Complex CGI application
- Demonstrates how to use native COBOL to create CGI programs which accept data from a form on a Web page and then redisplay
that data in another Web page.
- COBOL
-
- Airport Demo (Native)
- Demonstrates how to use a procedural console application to access the functionality defined in a legacy COBOL program.
- Preprocessor
- Shows a basic preprocessor and how to debug it.
- Tictac
- Demonstrates how use procedural COBOL.
- Data File Tools
- Demonstrates how to use procedural COBOL with some record layout definitions.
- Games
-
- COBOL Minesweeper
- Demonstrates how to create a random generator in native COBOL and how to use advanced console operations such as capturing
mouse events in the console.
- COBOL Snake
- Demonstrates how to create a random generator in native COBOL, dynamic memory allocation and advanced console operations.
- MFUnit Testing framework
- Demonstrate the capabilities of the Micro Focus Unit Testing framework.
- SQL
-
- SQL (Native OESQL) - Getting Started
- Demonstrates how to use static SQL with OpenESQL, performing a variety of SQL operations. It also demonstrates the use of
different styles of CONNECT statement.
- SQL (Native OESQL) - Behavior Demo
- Illustrates the use of OpenESQL compiler directives to assist in migrating database applications from the mainframe. The use
of the SQL(TRACELEVEL) compiler directive creates an OpenESQL trace file, OpenESQL.processID.log, within the project directory.
- SQL (Native OESQL) - Catalog Demo
- Displays information about all the data types supported by the data source, a list of all tables in the data dictionary, and
information about columns in the table 'orders'.
- SQL (Native OESQL) - Connect Demo
- A simple example of using static SQL with OpenESQL, performing a variety of SQL operations.
- SQL (Native OESQL) - Dynamic Demo
- A simple example of using dynamic SQL with OpenESQL, performing a variety of SQL operations. It is functionally equivalent
to the code used by the Static sample.
- SQL (Native OESQL) - Select Demo
- A simple example of using both singleton SELECT and cursor-based FETCH statements with OpenESQL.
- SQL (Native OESQL) - Whenever Demo
- Illustrates how to use EXEC SQL WHENEVER syntax with error handling. It also uses the MFSQLMESSAGETEXT variable for retrieving
errors messages longer than the 70 bytes available within the SQLERRMC field.
- Trace
-
- Consolidated Trace Framework - C
- Shows how to use the Consolidated Tracing Facility with C.
- Consolidated Trace Framework - COBOL
- Shows how to use the Consolidated Tracing Facility with COBOL.
- XML Extensions and Xcentrisity
-
- Xcentrisity Tutorial
- Includes a set of examples that demonstrate the use of XML Extensions and of the Business Information Server product.
- XML Extensions Example
- Demonstrates some of the capabilities of XML Extensions.
