∇∇36.001

The FORTRAN 77 standard used an older convention, spelling the name “FORTRAN” capitalized. The current convention is to use lower case: “Fortran 95”
References to online man pages appear with the topic name and section number. For example, a reference to the library routine GETENV will appear as getenv(3F), implying that the man command to access this man page would be: man -s 3F getenv
