ASP VBScript Subroutine Multiple Return Values

Hi friends,

Can subroutines return multiple values? If so how?

And will these return values have to be returned as an array? And again, how?

Thanks :-)

Hi again!
The easiest way to return more than one value from a FUNCTION is to use an array output:

<%
FUNCTION returnTwoAndFour(arg)
  Dim temp(2)
  temp(0) = arg
  temp(1) = "Four"
  returnTwoAndFour = temp
END FUNCTION

Dim test(2)

Response.Write returnTwoandFour("Two")(1)
Response.Write "<BR>"
Response.Write returnTwoandFour("Two")(0)
%>

What about from a Sub?

Well, SUBs are not created to return values. The can modifed the variables defined outside them (let's call them global variables) but they can not return values directly. Functions are used for that.
You may declare a variable outside your SUB, of array type and enough size. Then you may fill it inside your SUB.

Like this for example:

<%

  Dim Y(2)

  SetLocalVariable

  Response.Write Y(1)

Sub SetLocalVariable
    Y(1) = "Some text"
End Sub
