    list = who(connectionObj)

    Description

    list = who(connectionObj) returns a list of the variables that are in the connected data source connectionObj.

    If the data connection can access multiple definitions of the same variable (for example, in a data dictionary and in a referenced dictionary), the function lists each instance of the variable.
