How to make a .Net or JVM language?

Question

I am seeing all these new languages for .NET and JVM. How does one begin to make one?

I can\'t find any good documentation on JVM or MSIL specifications.

Answer 1

The Java Virtual Machine Specifications, Second Edition is available online.

One can target the JVM by having a writing a compiler that produces Java bytecode (which is defined in the JVM specifications.)

Or, by utilizing existing libraries such as Apache BCEL, one can produce valid class files through a Java program without having to actually manipulate the bytecode at the byte-level.
