How to declare a constant in BASIC?

Question

Unfortunately, I’m having trouble figuring out how to do some things, because Google is clogged with tutorials of “programming basics” and Visual Basic. So I have to ask: in old-skool BASIC, I know I can use constants like `#RED`, but how do I **define** a constant?

Answer 1

Just like you use Dim keyword to "dimension" a variable, you use the Const keyword to declare a constant. But unlike Dim, with Const you just assign the value to the constant. From that point forward it can't be changed.

Public Sub PrintConstant()

Const MAX_RAM = 2048

Const TXT_MB = "Megabytes"

Const TXT_GB = "Gigabytes"

Debug.Print MAX_RAM & " " & TXT_MB

Debug.Print MAX_RAM & " " & TXT_GB

End Sub
