ORA-06513: PL/SQL: index for PL/SQL table out of range for host language array

For the past 5 years or so we have been using the ODAC components to access an Oracle stored procedure. this stored procedure returns string values. we have recently increase the number of values returned as Tparams to over 64. appearently we have reach some type of limitation of the TOraParams object.

Is there anyway to increase the number of parameters that can be successfully returned?

It looks as if I am using version 3.50, Delphi 6

Please specify the value of the Length property of the parameter. Length must be equal or more than number of values.

but rather the number of parameters in the TOraStoredProc.PArams list.

we have over 65 parameters

We could not reproduce the problem. Please send to odac*crlab*com a complete small sample that demonstrates the problem, including script to create server objects.
Also specify the exact version of Oracle server and client. You can see it in the Info sheet of TOraSession Editor.

You can also try to upgrade ODAC to the last build of ODAC 3 (3.90.0.61) or to a newer version, and check if the error occurs.
