How to define global variables using scripts

Hi folks,

I want to declare and use self defined global variables across a complete test flow execution. The Test Flows encompass multiple script (JScript) files and multiple functions (I dont want to use Project or Project Suite Variables).

I tried to do the following but its not working:

//Defined a script file variables.sj. This file had this code:

var myGlobalVariable = 9;
Log.Message("01. Global value of 'myGlobalVariable': " + myGlobalVariable);

function setVariables()
{
myGlobalVariable = 10;
Log.Message("02. Local value of 'myGlobalVariable': " + myGlobalVariable);
}

Log.Message("03. Global value of 'myGlobalVariable': " + loginArray);

//Defined another script file useGlobalVariables.sj. This file had this code:

//USEUNIT variables

function useGlobalVariablesFunction()
{
variables.setVariables();

//I know this function above will not set the values outside its scope.

log.Message("Calling global variable: " + variables.myGlobalVariable);
}

Executing the function 'useGlobalVariablesFunction' throws an error: 'Object doesn't support this property or method'
