Hi
The easiest way would to be define global variables in the variables file and example of this is

$global:variable1 = " this is variable 1"
$global:variable2 = " this is another one"

in your main script call the variable file like this

.\myvariables.ps1
write-host $variable1

Then at the end of the main script delete the global variables using the following command

 Remove-Variable variable1 -scope global

There are many methods that  can be used , another is create an xml file as that contain the variables.

then import them.

to import the variables  you could use the following.
example xml file is
<?xml version="1.0" encoding="utf-8"?>
<Config>
  <SQL>
    <SOURCE>D:\SQL2008sp2</SOURCE>
    <PCUSOURCE>D:\SQL2008sp2\PCU</PCUSOURCE>
    <CUSOURCE>D:\SQLSPandCu\cu10</CUSOURCE>
    <SQLPort>1433</SQLPort>
    <DriveLetter>D</DriveLetter>
 </SQL>
</Config>

Open in new window


then in your main script add
$ConfigFile = (get-item "myvariablesxml").fullname
[xml] $xmlinput =  get-content $ConfigFile

you can then access the item as follows

$sqlport = $xmlinput.config.sql.sqlport



I hope you find this helpful
