Re: Compiler String Efficiency

Although not all this information is available, I would consider 1 and 2
equal (1 creates a String before passing it as an argument).

3 must create two different strings. I see no reason for this.

Note: If the argument is by reference, then the address of the string is
passed. This is quite a bit more efficient that ByRef string arguments,
which cause VB to create a second string and pass the address of that.
