A unique aspect of Java that allows code compiled on one machine to be executed on a machine of a different hardware platform is Java's

Java's bytecode

Explanation:

To execute its operations, java programming languages uses bytecodes.

These bytecodes are literally instructions of a java virtual machine (or JVM). They are generated in form of a class file as soon as the java program is ran and executed. In other words, the java compiler compiles the code and generates the bytecode.

As soon as the bytecode is generated, it can be transferred to a different machine and platform completely and one can run this bytecode on this different machine.

a macro is a tool that allows you to automate tasks and add functionality to your forms, reports, and controls. for example, if you add a command button to a form, you associate the button's onclick event to a macro, and the macro contains the commands that you want the button to perform each time it is clicked.
