Marc,

You didn't really ask a question... simply stated what you were trying to do... and you also didn't state what problem you are having, other than you can't find documentation. Perhaps something in the following will help you understand what's going on...

Other than that, ASK A QUESTION!

Good luck!

Title:                 Fortran OCI Guidelines on HP MPE 

Creation Date:         10 May 1994 

Abstract:              This article shows how to use the Oracle Call 
                       Interfaces with Fortran 77/iX.  EQUIVALENCE 
                       forces alignment of INTEGER*2 variables on 
                       word boundaries.  All OCI routine parameters 
                       are required.  Source code of a sample Fortran 
                       OCI program is included.

Discussion:

Using the Oracle Call Interfaces (OCI) on HP MPE systems requires some special preparation of the source code. This article outlines these measures and concludes with a sample Fortran OCI program based on the source code provided in the "Programmer's Guide to the Oracle Call Interfaces Version 1.5" (compatible with RDBMS Version 6.0.33.2.24). Note that several routines available in OCI Version 1.5 are obsolete or obsolescent in OCI Version 7.0.

For backward compatibility and memory conservation, Fortran 77/iX aligns
INTEGER*2 arrays on half-word, or two-byte, boundaries. However, the C routines that comprise OCI expect all variables to be aligned on full-word, or four-byte, boundaries.

Solution:

The EQUIVALENCE statement is used to force alignment of the Logon Data Area (LDA) and Cursor Data Area (CDA) by declaring equivalence of these arrays to dummy INTEGER*4 arrays of the same number of bytes. For example:

      INTEGER*4         foo(16) 
      INTEGER*2         LDA(32) 
      EQUIVALENCE       (foo,LDA) 
 
      INTEGER*4         foo2(16,2) 
      INTEGER*2         CURS(32,2) 
      EQUIVALENCE       (foo2,CURS)

Parameters to some OCI routines documented as optional in the Programmer's Guide are in fact required for OCI programs on HP MPE. The ODEFIN, ODSC, OBNDRV and OBNDRN routines require at least dummy variables for all parameters. Square brackets in the documentation indicate that the parameter is an address.

C routines expect parameters to be passed by reference or by value. Fortran 77/iX passes all parameters by reference by default. HP provides two mechanisms for controlling the default: the $ALIAS compiler directive and the %REF/%VAL parameter modifiers. The sample uses the %REF/%VAL extensions as available on some other platforms. For example:

CALL OLON(LDA(1), %REF(UID), %VAL(UIDL), %REF(PSW), %VAL(PSWL), 1 %VAL(0)) In conclusion, Fortran OCI programs can be used on HP MPE systems once some platform-specific necessities are taken into account. The sample program, once prepared according to the above guidelines, runs correctly.

Sample Fortran Source Code

The sample source code of this program follows.

C ===================== start of Fortran source code 
 
$tables on 
      PROGRAM FSAMP

C     FSAMP IS A SIMPLE EXAMPLE PROGRAM WHICH ADDS NEW EMPLOYEE 
C     ROWS TO THE PERSONNEL DATA BASE.  CHECKING 
C     IS DONE TO INSURE THE INTEGRITY OF THE DATA BASE. 
C     THE EMPLOYEE NUMBERS ARE AUTOMATICALLY SELECTED USING 
C     THE CURRENT MAXIMUM EMPLOYEE NUMBER AS THE START. 
C     IF ANY EMPLOYEE NUMBER IS A DUPLICATE, IT IS SKIPPED. 
C     THE PROGRAM QUERIES THE USER FOR DATA AS FOLLOWS: 
C 
C        Enter employee name  : 
C        Enter employee job   : 
C        Enter employee salary: 
C        Enter employee dept  : 
C 
C     IF "0" IS ENTERED FOR THE EMPLOYEE NAME, THEN THE PROGRAM 
C     TERMINATES. 
C 
C     IF THE ROW IS SUCCESSFULLY INSERTED, THE FOLLOWING 
C     IS PRINTED: 
C 
C     ENAME added to DNAME department as employee # NNNNN 
C 
C     THE MAXIMUM LENGTHS OF THE 'ENAME', 'JOB', AND 'DNAME' 
C     COLUMNS WILL BE DETERMINED BY THE ODSC CALL. 
C 
C     NOTE: VAX FORTRAN, BY DEFAULT, PASSES ALL CHARACTER STRING
VARIABLES 
C           (i.e. VARIABLES DECLARED AS CHARACTER*N) BY DESCRIPTOR.
SINCE OCI 
C           ADDRESS PARAMETERS MUST BE PASSED BY REFERENCE, ALL
CHARACTER 
C           STRING VARIABLES IN THE FOLLOWING PROGRAM ARE PASSED USING
THE 
C           VAX FORTRAN EXTENSION: %REF. 
C           TO COMPILE THIS PROGRAM ON OTHER PORTS, SIMPLY REMOVE THE 
C           REFERENCES TO %REF.

IMPLICIT INTEGER (A-Z) C MPE/iX need these EQUIVALENCES to force Fortran to align the arrays to
C 4-byte boundary as expected C.

C MPE/iX use more space here because of trailing blanks before continuation
char

      CHARACTER*92      INS 
      CHARACTER*38      SEL

C (MPE/iX) These variables are needed for calls to ODEFIN, ODSC, OBNDRV and
C OBNDRN because they need pointers to valid addresses. Parameters are not
C optional. Square brackets in doc indicates the parameter is an address.
