Fortran—especially of that era—is a simple language.  It wasn't clear to me 
what the end goal was of the conversation.  Starting with old DEC-10 code and 
trying to get it to run on Linux?  Anyway, none of the Fortran code that was 
posted here was difficult at all to understand.  Of course, I know it from 
being proficient in Fortran for decades.  But, a slight but of Google'ing would 
have easily solved any porting problems.  File formats being exchanged across 
different platforms is another issue.  And, language independent.  I'm sure you 
know that RMS file formats are far richer and expressive of their content than 
a non-descriptive stream of bytes.  Oh, except for the magic 16-bits at the 
front of something executable.  Or the suffix that help you infer the 
semantics.  A file system with limited metadata forces such hacks.
