How to declare multiple variables with specifying type using As in VBA?

Question

According to this documentation by Microsoft, the following code can be used to make sure;

a, b, and c are all Single; x and y are both Double

Dim a, b, c As Single, x, y As Double, i As Integer  
> a, b, and c are all Single; x and y are both Double  

The logic behind this is as follows

You can specify different data types for different variables by using a separate As clause for each variable you declare. Each variable takes the data type specified in the first As clause encountered after its variable name part.

However, when I checked with the debugger or MsgBox VarType(a) output, this is not the case.

As you can see, it appears that As is only working for the variables right before itself, ie., c, y and i. All others are Variant/Empty and VarType returns 0.

Is this just the documentation being wrong, or am I missing something obvious?

Answer 1

The documentation you've linked to isn't wrong, but it's written for VB.NET and not VBA.

In VBA, as you've observed, any variable declarations that aren't immediately followed by As <type> will be Variant.

Therefore you'd need to write:

Dim a As Single, b As Single, c As Single, x As Double, y As Double, i As Integer
