Here are some things to try edit the document name above by typing in the input field. The difference lies in the way they read the source code. A compiler translates source code to machine code, but does not execute the source or object code. Compiler converts the code of the complete source file at once whereas interpreter does the same job. A compiler passes over a whole program before translating it into object code. If you want a compiler interpreter for that use, you want the p6 compiler, which contains things like file access extentions and a lot more.
So, a program written for example in a highlevel language such as java cannot be run directly to execute a computer program written in the high or lowlevel language, it must be first translated.
