Hi,

I'm still learning all this VBA stuff, so apologies if this is simplistic,
but...

I have a set of macros embedded into a worksheet which all work fine.
Several of these use the same variable.

The value of this variable is the content of a single defined cell on a
specific sheet. the user inputs this value, so it can change, but not between
iterations of the macros (hope this makes sense so far).

What I would like to do is declare the variable once across all the macros,
rather than having to declare it each time and send the code off to look for
it.

I don't seem to be able to declare a Const as a Range, so I tried to do it
as a String, like this:

Const Trigram As String = Sheets("User Data").Range("b2")

but the compiler doesn't like that at all (the error is "Constant expression
required")

I also tried:
Dim ReadOnly Trigram As Range = Sheets("User Data").Range("b2")

this time the error highlighted Trigram and is "Expected: end of statement"

Questions:
a) I'm putting these immediately below the Option Explicit (ie above the
line delimiting the first sub() ) - is this the correct place for them?
b) What is the correct way of achieving my intent?

TIA

Dave

A constant is a constant so you can not declare it by pointing it to
something that might change. A variable needs to be initialized in a sub or
function. It can not be outside of that. If it was me I would be inclide to
just use...
Sheets("User Data").Range("b2")

when I need the value. If you want though you could use a function something
like this...

public function Trigram () as string
Trigram = Sheets("User Data").Range("b2").value
end function

Now you just use it the same way you would a variable.

What about

Const Trigram As String = Sheets("User Data").Range("b2").Value

a) Yes but I believe you add the word "Public" before the word "Const"
b) Looks like you figured it out already :-)

Jim,

Thanks for the prompt response - exactly what I needed.

Have you tried this or anything similar...

Const Trigram As String = Sheets("User Data").Range("b2").Value

it won't compile at my end. The only thing you added was the .value and
value is the default property of a range so it is there by default.
Additionally declaring
Const
or
Public Const
is exactly the same thing since the default scope is public.

Searching into old posts helps...
This is what I needed.
