FUNCTION xpfGetTemporaryVariableValue(tempVariable : STRING;
                                      options      : INTEGER)
                                      value        : GENERIC;

Function to get the value of an EDMtemporaryVariable. An EDMtemporaryVariable is a LOCAL or GLOBAL variable in an EDMexpressX schema that is defined at run-time in an EDMvmSession. Hence, an EDMtemporaryVariable cannot be referenced by name in the source code of the actual EDMexpressX schema, since such variables are not known at compile time. An EDMtemporaryVariable is only known in the EDMsession that defines it, i.e., all EDMtemporaryVariables are deleted when an EDMvmSession is closed. The function has variable number of arguments, i.e., it can be invoked with a minimum of 1 argument and a maximum of 2 arguments.
