Question

ABC23 is a invalid variable in visual basic why

Answer 1

Answer:

characters in length.

Generally, you shouldn't use any names that are the same as the function, statement, method, and intrinsic constant names used in Visual Basic or by the host application. Otherwise you end up shadowing the same keywords in the language. To use an intrinsic language function, statement, or method that conflicts with an assigned name, you must explicitly identify it.
