Using this code and NOT passing any parameters works fine. Finds the object on the AS400 and kicks off the job.
It's when I add the parameter data that I error out..

This is my code..

Dim ConnString As String
ConnString = "Provider=IBMDA400; Data Source=" + myas400sys + "; User ID=" + MYUSER + "; Password=" + MYPASSWORD + ";"

Dim myConnection As New OleDb.OleDbConnection
myConnectionConnectionString = ConnString

Dim myCommand As New OleDb.OleDbCommand("CALL TGCLOCKRCV.TGDSQL(?)", myConnection)
myCommand.CommandType = CommandType.Text
myCommand.CommandText = ("CALL TGCLOCKRCV.TGDSQL(?)")

'setup the parameters
myCommand.Parameters.Add(New OleDb.OleDbParameter)
With myCommand.Parameters(0)
.ParameterName = "SERIAL"
.Direction = ParameterDirection.InputOutput
.Value = "STRING1"
.OleDbType = OleDb.OleDbType.Char
.Size = 8
End With

Dim results As String

Try
myConnection.Open()
Catch ex As Exception
MYERRMSG = ex.Message.ToString()
End Try

Try
myCommand.ExecuteNonQuery()
SerialNbr = SerialOut.ToString()
Catch ex As Exception
MYERRMSG = ex.Message.ToString()
End Try

myConnectionClose()

The error message from the AS400/SQL/everyone

SQL0204: TGDSQL in TGCLOCKRCV type *N not found.
Cause . . . . . : TGDSQL in TGCLOCKRCV type *N was not found.
If the member name is *ALL, the table is not partitioned.
If this is an ALTER TABLE statement and the type is *N, a constraint
or partition was not found. If this is not an ALTER TABLE
statement and the type is *N, a function, procedure, trigger
or sequence object was not found. If a function was not found,
TGDSQL is the service program that contains the function.
The function will not be found unless the external name and
usage name match exactly. Examine the job log for a message
that gives more details on which function name is being
searched for and the name that did not match.
Recovery . . . : Change the name and try the request again.
If the object is a node group, ensure that the DB2 Multisystem
product is installed on your system and create a nodegroup
with the CRTNODGRP CL command. If an external function was not found,
be sure that the case of the EXTERNAL NAME on the
CREATE FUNCTION statement exactly matches the case
of the name exported by the service program.


Any help out there???

Thanks
