IBM VS COBOL II Compiler Desupported

The IBM VS COBOL II compiler has been desupported. However, the string "IBMVSCOBOLII" is still used as the value of the compiler name parameter to represent any COBOL compiler you choose to use. The value IBMVSCOBOLII should still be used and does not create a dependency on any specific version of the compiler.
