Syntax
/x[-]
The Visual J++ compiler supports the Java language specification. In addition, it may offer a number of features beyond those required by this specification. These features are available by default, but are not available when the /x option is specified.
Use the /x option if you plan to port your program to other environments. The /x option tells the compiler to treat extended keywords as simple identifiers and to disable the other Microsoft extensions.
Note To disable this option, use a dash (–) after the option on the command line.
Example
The following command ignores any Visual J++ extensions used in the myClass.class file:
JVC /x myClass.java
