PowerShell Powershell Modules Exporting a Variable from a Module
Example
$FirstName = 'Bob'
Export-ModuleMember -Variable FirstName
To export a variable from a module, you use the Export-ModuleMember command, with the -Variable parameter. Remember, however, that if the variable is also not explicitly exported in the module manifest (.psd1) file, then the variable will not be visible to the module consumer. Think of the module manifest like a "gatekeeper." If a function or variable isn't allowed in the module manifest, it won't be visible to the module consumer.
Note: Exporting a variable is similar to making a field in a class public. It is not advisable. It would be better to expose a function to get the field and a function to set the field.
