Visual Basic.NET Programming. Beginner Lesson 11. Logical and Relational Operators 2

This is the eleventh in a series of computer science video tutorials for beginners, about programming with Visual Basic.NET (VB.NET) in Visual Studio. It follows on from the previous lesson about relational and logical operators. In this lesson you will learn about the logical operators, NOT, AND and OR. You will also learn how relational operators, including equal to, greater than, less than, greater or equal to, less than or equal to and not equal to, can be used to perform complex tests in the condition clause of an IF statement. The importance of validating user input to ensure robust programs that don’t crash is emphasised, as is the importance of careful and thorough testing of every execution path in a program.

I searched but could not find if VB allowed a variable to be sandwiched between relational operators, i.e.
1 <= x <=10. I guess the closest would be set membership.
