               inout nArraySize  : number optional,
               out   sName       : array of string(30) optional,
               out   nDatatype   : array of number optional,
               out   nMode       : array of number optional, 
               out   nSize       : array of number optional ): boolean;

Parameter	Description
hConnection	Handle to an Oracle database connection
sObjName	Name of the PL/SQL procedure or function, including optional schema and package name. Quoted names are accepted. Synonyms are also accepted and are translated.
nArraySize	Array size of the sName, nDatatype, nMode and nSize parameter. This parameter receives the actual number of array elements described.
sName	String array receiving the name of each parameter of the PL/SQL procedure or function. 注: The size of each string buffer must be exactly 30 characters.
nDatatype	Array receiving the data type of each parameter of the procedure or function. See Oracle data types for a list of all data types.

    nMaxArr, i : number;
    sParam     : array[MAXARR] of string(30);
  begin
    OraLogon(hConnect, "username/password@orclnet2");
    OraOpen(cCursor, hConnect);
    nMaxArr := MAXARR;
    OraDescribeSP(hConnect, "sp", nMaxArr, sParam);
    for i := 1 to nMaxArr do
      write("Param: "); write(sParam[i]); writeln;
    end;
    ...
