LF Fortran 95

Fortran 77 Compatibility

This chapter discusses issues that affect the behavior of Fortran 77 and Fortran 90 code when processed by LF95.

Different Interpretation Under Fortran 95

Standard Fortran 95 is a superset of standard Fortran 90 and a standard-conforming Fortran 90 program will compile properly under Fortran 95. There are, however, two situations in which the program's interpretation may differ.

Different Interpretation Under Fortran 90

Standard Fortran 90 is a superset of standard Fortran 77 and a standard-conforming Fortran 77 program will compile properly under Fortran 90. There are, however, some situations in which the program's interpretation may differ.

Obsolescent Features

The following features are obsolescent or deleted from the Fortran 95 standard. While these features are still supported in LF95, their use in new code is not recommended:
