Direct Migration of Object Code(Compatibility Mode) The fastest way to move your programs from an MPE V system to MPE/iX is to simply transfer the object code from one system to the other. Your programs can then be run on MPE/iX in compatibility mode. This works for programs produced by either the FORTRAN 66/V or HP FORTRAN 77/V compiler. If there are data files associated with your program, you can move them also (without needing to change the representation of the data). Use the MPE V STORE command to transfer the files onto magnetic tape. Next, on the MPE/iX system, use the RESTORE command to move the files from the tape. You can now use the RUN command to run your program just as you would on the MPE V system. Note, however, that programs run in compatibility mode do not take advantage of the optimizing compiler nor of the improved performance capabilities of HP's Precision Architecture. To take advantage of these improvements, you must run your programs in native mode, which is explained in the next section.
