The compiler can not know if the operation x/a-b will leads to division by zero until the execution. C# and VB.NET - both use value types and reference types, but the characters you type to define them are different); in other cases, two languages are syntactically similar, but the Oct 12 '11 at 10:30 8 A separation between lexing and parsing stages is entirely artificial, it is nothing more than an optimisation. https://en.wikipedia.org/wiki/Syntax_error
