How is it possible to reference a variable within a variable in the new scripting system of VSTS?
e.g:
RemoteMachineFqdn: somemachinename.somedomain
RemoteMachineUncPath: \\$(RemoteMachineFqdn)\c$\
In the aforementioned example, assume there are tasks that both use CMD and Powershell scripts with the given variables. I tried using the the variables by referencing their values from the environment but it does not work for both scenarios since %variable% works only in CMD and $env:variable - only in Powershell.
What is the standard way to do it?

What you are looking for is Logging Commands. To invoke a logging command, simply emit the command via standard output. For example, from a PowerShell task:
##vso[task.setvariable variable=testvar;]testvalue
This example sets a variable in the variable service of taskcontext. The first task can set a variable, and following tasks are able to use the variable. The variable is exposed to the following tasks as an environment variable.
