NOTE: Before FORTRAN 90, most FORTRAN compilers enforced fixed-format source code, a carryover from IBM punch cards 1. comments must begin with a * or C or !in column 1 2. statement labels must occur in columns 1-5 3. continuation lines must have a non-blank character in column 6 4. statements must start in column 7 5. the line-length may be limite...

"Retro" Fortran IV

A retro example of a FORTRAN IV (later evolved into FORTRAN 66) program deck is available on the IBM 1130 page, including the IBM 1130 DM2 JCL required for compilation and execution. An IBM 1130 emulator is available at IBM 1130.org that will allow the FORTRAN IV program to be compiled and run on a PC.

What is interface block in Fortran 90?

Because we will be focusing on external subprograms, it isessential that we make use of a feature of Fortran 90 known asthe INTERFACE block. This block is safety feature which allowsmain programs and external subprograms to interfaceappropriately.

What is a Fortran 90 pointer arithmetic?

Fortran 90 pointers are "associated" with well-defined "target" variables, via either the pointer assignment operator ( =>) or an ALLOCATE statement. When appearing in expressions, pointers are always dereferenced; no "pointer arithmetic" is possible.
