What is the importance of Option Explicit statement in VBA?

Option Explicit makes the declaration of variables mandatory in VBA. To make explicit declaration of all variables mandatory, Option Explicit statement must appear before any procedures at file level. Option Explicit ensures that all variables are explicitly declared within that respective module and if an attempt is made to use undeclared variable, compile time error occurs.

What is the use of Option Base statement in VBA?

Option Base statement is used at module level. It declare the default lower bound for Array subscripts. For example, if we use Option Base 1, it will make the lower bound of each Array in that module to start from 1 instead of 0. Option Base statement has no impact on ParamArray parameter type used in procedures or functions. The array variable declared as a ParamArray has a lower bound value of 0, regardless of Option Base statement setting at module level

Specify the difference between passing variables ByRef and ByVal?

If an argument or variable is passed ByRef, it means a  reference or memory address of that argument is passed to the called procedure in that particular case. If the value of the argument changes in the called procedure, the modified value of that argument reflects in calling procedure.

If an argument or variable is passed ByVal, it means actual value of variable is passed to the called procedure in that particular case. If the value of the argument changes in the called procedure, the modified value is only limited to the called procedure and the new value does not reflects in calling procedure.

What is the default method of passing parameters in a procedure?

By default, parameter is passed by reference i.e. ByRef.

Can we pass an Array by value (i.e. ByVal) to procedure?

No. Arrays are always passed by reference.

What will happen if we try to pass an Array by value to a procedure?

If we try to pass an Array by value, it will generate a compile time error.

What will happen if we use ReDim without Preserve?

Using ReDim without Preserve resizes a dynamic array but destroys its existing contents.

Is it possible to change a static array into a dynamic array?

No. It is not possible.

What will happen if we try to use ReDim for a static array?

Since size of static array is fixed, it will generate a compile error, if an attempt is made to resize the static array using ReDim statement.

Specify difference between SUB procedure and FUNCTION procedure?

1. SUB procedure cannot return a value but FUNCTION procedure return a value.
2. SUB procedure cannot be invoked directly from a worksheet cell , whereas FUNCTION procedure can be invoked directly from a worksheet cell.
3. SUB procedure can change the contents or format of any cell, whereas FUNCTION procedure cannot change the contents or format of any cell.
