In some suitable application (Excel, for example) create a simple subroutine to display a message.  Your subroutine should take one argument - the message to be displayed - and produce output like this:

You can pass different messages to your subroutine to display different message boxes

If you still have time, try writing a different subroutine to unprotect or protect a given worksheet.  This subroutine should take 2 arguments:

  • The name of the sheet to be protected or unprotected
  • Whether to protect the sheet or not (a Boolean argument)

Note that to protect or unprotect a worksheet you just apply the Protect or Unprotect methods. 

Try running your  macro using commands like this to test it:

Two sample commands to test your macro

If you still have time, try making the second argument optional, so that by default your subroutine will protect a sheet if the protection status is not explicitly given when the macro is run.
