Compiling F Programs

Since F is a subset of Fortran 95, any Fortran 95 compiler will compile an F program. However, to impose strict F syntax, a compile with explicit support for F can be used.

The G95 compiler supports the F standard and will enforce the standard when -std=F is used:

g95 -std=F my_program.f95
