Using defined macros in a VBScript

[ChrisF]

I'm using VBPro v7.2

I set up macros to start my script, for example

macro name = PROJECT_DIR
macro value = C:\My Projects

I can then use the macroin subsequent steps, like copying files, for example

source dir = %PROJECT_DIR%\source

But now I want to use the macro in a step that has a VBScript, and the macro NEEDS to be inside quotes. So without the macro, I do

dbFile = "C:\My Projects\myFile.db"

How can I do the equivalent of this instead?

dbFile = "%PROJECT_DIR%\myFile.db"
