Problem with dg4msql and table-valued functions

Question

Have configured dg4msql to connect from my oracle db to ms sql server.
Am able to do simple SELECTs from ms sql tables like:
select * from "sys"."procedures"@dg4msql;
or
select * from "dbo"."SomeTable"@dg4msql;
But am unable to do a SELECT from a table-valued function:
select * from "dbo"."GetData"@dg4msql('param1value');
or
select * from "dbo"."GetData"('param1value')@dg4msql;
In both cases I get:
ORA-00933: SQL command not properly ended
It does not like the parameters portion of the query ("('param1value')")
initdg4msql.ora:
HS_FDS_CONNECT_INFO=[svr1]//mydb
HS_FDS_TRACE_LEVEL=OFF
HS_FDS_PROC_IS_FUNCT=TRUE
HS_FDS_RESULTSET_SUPPORT=TRUE
Have tried the other set of params:
HS_FDS_PROC_IS_FUNCT=FALSE
HS_FDS_RESULTSET_SUPPORT=TRUE
Same story. After changing the init*** file have bounced both Listeners (DB and Gateway), reconnected, and re-run the query.
Have I missed something?
Any help is greatly appreciated!

Sorry, but for me it looks you did not get the problem.

Result Sets and Stored Procedures
The Oracle Database Gateway for SQL Server provides support for stored procedures which return result sets.
By default, all stored procedures and functions do not return a result set to the user. To enable result sets, set the HS_FDS_RESULTSET_SUPPORT parameter value to TRUE.
PL/SQL Program Fetching from Result Sets in Sequential Mode
-- Execute procedure
out_arg := null;
refcurproc@MSQL('Hello World', out_arg, rc1);
Somewhere in this forum I've seen a message that the syntax "SELECT ... FROM sp@db(param1, param2)" works.
Anyway, even with the PL/SQL block the error message is the same - ORA-00933 "SQL command not properly ended"
and the cursor (* in SQL*PLUS) is put just at the first bracket.
