Does Intel Composer XE 2011 contain support for FORTRAN 77?

[langloisc]

We are currently looking at purchasing another cluster for our agency and we require the Intel Fortran 77 compiler for one of our models. Is this included in the 2011 suite or did they get rid of it?

Fortran 77 is a subset of Fortran 90. You use 'ifort' command for Fortran 2003, 95, 90, and 77. So no, there is not a separate f77 command, one simply uses 'ifort -fixed' or name your files .f77, .f, .F

There were many vendor extensions in the 'old days' that are supported by ifort too, particularly the popular DEC extensions.

A minor correction - .f77 is not recognized as a file type. .f or .for for fixed-form souce. The Intel compiler supports Fortran IV (Fortran 66), Fortran 77, 90, and 95, most of 2003 and some of 2008. In some cases, you may need a compiler option to select a F77 interpretation that conflicts with later standards, but that is unusual. Most real Fortran 77 code will compile and run fine without anything special.
