Calling a Sub and returning a value

Question

This might seem like an insanely easy question  but I can t seem to find an answer anywhere to it  I d like to think that I am decent at VB but while I was learning javascript the other day I found something that seemed awesome and now I can t figure out how to do it in VB   In javascript it looks like this   var someValue   getThatValue    It s both calling and setting the value from the getThatValue   sub  what is the VB equivalent      Edit  I ve tried doing this      private sub main          dim value   getValue           do something with value    end sub     private sub getValue          return 3    end sub   That doesn t seem to work  how can I get that to work

You should be using a Property   Private  myValue As String Public Property MyValue As String     Get         Return  myValue     End Get     Set value As String           myValue   value      End Set End Property   Then use it like so   MyValue    Hello  Console write MyValue

Sub  don t return values and functions don t have side effects  Sometimes you want both side effect and return value  This is easy to be done once you know that VBA passes arguments by default by reference so you can write your code in this way  Sub getValue retValue as Long              retValue   42  End SUb   Sub Main       Dim retValue As Long     getValue retValue           End SUb
