[AccessD] Learning .Net -- PHP Instead?

True, but why would you construct it that way?  You're essentially
describing a callback.  And you CAN nest Do Loops, even in VBA.

Why?

Code is used to make a functional project.  It's primary purpose is to
do just that.  After that, the code should be organized and readable,
and as optimized as possible.  With proper objects and function, this
can be accomplished.  With the exception of errorhandling a goto
statement is going to be a rare case, but NOT an excluded case, to make
the code readable and organized.  In my example, making a do loop would
require addition logic on each step, because when you exit a loop, it
starts all over.

A Do Loop cannot have extra 'loop' statements.  

Ie:

Do

'some condition is met: then Loop

Loop

Can't do that.  You can do that with a Goto statement.

A Do...Loop would be preferable to Goto.

I think it should be said that you shouldn't use GOTO to prevent
breaking your code into more logical parts.  Errorhandling is a
situation which would allow Goto then.  There is another situation.
Let's use an imaginary 'Phone' object that is going to make a call, and
it needs to try 20 times unless successful:

Dim obj as Phone
Dim intTries as Long
Dim blFailed as Boolean
intTries=0
Set obj=New Phone

StartOfCall:

blFailed=True
intTries=intTries+1
If intTries=21 then Goto
