@Leo Val("$glob:Sting_Track7") requires quoted argument as documented but does not work as desired when using an expression as the argument.
Is it possible (now or in the future) to use an expression as the argument?
For example, instead of Var("$glob:Sting_Track7") use:
//Example Modifier syntax that does not work (Dopus 13.10)
@eval varValue = Val("$glob:Sting_" + "Track7")
@eval varPrefix = "$glob:Sting_"
@eval varSuffix = "Track7"
@eval varValue2 = Val(varPrefix + varSuffix)
