PInvoke Example

The supplied PInvoke sample demonstrates Platform Invoke.

See the Pinvoke example, which is with the examples. See Start > All Programs > Micro Focus Visual COBOL > Samples. This example contains the following of interest:

Pinvoke.cbl. This program is managed COBOL. It uses the standard COBOL CALL statement to call the sub program and to send it the message buffer to display, as follows:
```
       call "SUB" using messageBuffer
```
sub.dll. This program is existing native COBOL.
The built sub.dll is included as a reference in the project, whereas the source file sub.cbl is not included, because it is native code and not compiled as part of the project. You can view the source file by opening it from the File menu.

To run the example:

Build the solution by clicking Build > Build pinvoke.
Step through the program, using Debug > Step into.
