Compiler Errors

field of a union cannot derive from a conformant/varying array or its pointer equivalent The conformant array cannot appear alone in the union but must be accompanied by the value that specifies the size of the array. Instead of using the array as the union arm, use a structure that consists of the conformant array and the identifier that specifies its size.
