How can I get all values of a setting of a Production item programmatically?

I wish to retrieve all the setting values for a given production. I have found

   Set tSC=##class(Ens.Director).GetProductionSettings("EXC.EXC",.tSettings)    WHERE EXC.EXC is the name of the Production

My question is

1) Does .tSettings contain the settings?

2) if  yes, how can I show them.

3) if no, how do I get the settings values?
