Delphi 1.0 and ORACLE 7.3 Stored Procs

Hi!

I made a stored proc in ORACLE 7.3. I tried to use it with TStoredProc
component in Delphi 1.0.
I can select the name of this stored proc, but I cannot get the
parameters (IN parameters in the stored proc) automatically?

Is there any problem with ORACLE or Delphi? How can I solve this
problem???

Thanks in advance, bye Miklos Merges
