DOWNLOADING/INSTALLING

You can download Ratfor90 from http://sepwww.stanford.edu/sep/bob/ratfor90/ratfor90. You might need to change the first line of the code indicating where perl is on your system.

You can convert from Ratfor90 to Fortran90 on the command line by:

ratfor90 < input.r90 > output.f90

If you wish to use expanded SEP command line, history file manipulation, and self-documentation abilities add the -sep -SOURCE /my/source/location flags. An alternate approach is to use the SEP makefile rules which are explained in Reproducible electronic documents. If you follow this approach you will need to:

• install ratfor90 in /usr/local/bin/ratfor90 or edit the Prg.defs.top file.
• set the environmental variable RATF90 to yes ( setenv RATF90 yes). If you are using the SEP setup you can add this line to your Setup/cshrc.machinetype [e.g. cshrc.sgi, cshrc.i586, etc.]
• name your Ratfor90 files:
  • using Fortran90 syntax .r90.
  • using Fortran90 and SEP allocation conventions .rs90.

By setting the environmental variable RATF90, SEP style ratfor77 code, normally indicated by the .rt, .rs, and .rst suffixes will converted to Fortran90 by Ratfor90 and compiled. These rules are in the updated version of the SEP makefile rules so if you have a previous version you will need to download a new one.
