Factors Affecting Migration
Many HP FORTRAN 77/V programs require no more than recompilation by the
HP FORTRAN 77/iX compiler to run correctly, since the version of FORTRAN
77 accepted by the HP FORTRAN 77/iX compiler is a superset of that
accepted by the HP FORTRAN 77/V compiler.
HP FORTRAN 77/V programs containing certain features may need some
modification to be compiled by the HP FORTRAN 77/iX compiler and to run
correctly after compilation. These features are described in Chapter 8
("Differences").
If a program has any of the features described in Chapter 8, you may need
to make some changes to the program before compiling it with the HP
FORTRAN 77/iX compiler. These changes are described in Chapter 9
("Source Program Conversion").
Changes may also be required to HP FORTRAN 77/V data files before they
can be used by an HP FORTRAN 77/iX program. These changes are described
in Chapter 10 ("Data File Conversion").
