Setting Java System Variables

Some Visual COBOL functions rely on specific parameters that can be specified by setting Java system variables, which are simple key-value pairs.

These variables can generally be set in two different ways:

By using the "-D" Java virtual machine (JVM) argument on start up. As all JVM arguments, the parameter must be defined under "-vmargs" and has the following syntax:
- -DmyVariable=myValue
These arguments can be configured, for example, in the <Eclipse-root-folder>\eclipse.ini file.

Example:
```
-vmargs
-Dteamdeveloper.defaultConfigurationsPath=C:\default_configs.xml
```
By using the System.setProperty(…) Java method at runtime.

Visual COBOL supports an additional way to define Java system variables by parsing the <Eclipse-root-folder>\mfeclipse.ini when started. Variables are simply defined by key value pairs.

Example:

teamdeveloper.defaultConfigurationsPath=C:\default_configs.xml

Note: The value must be a valid Java string when using the mfeclipse.ini file. Since "\" is an escape character, either "\\" or "/" can be used for file path separators. If the file mfeclipse.ini does not exist, it can be created manually.
