  Although fixed length records are usually used with indexed and relative 
files, variable length records are supported for both indexed and relative 
files.  See "Guide to OpenVMS File Applications", section 2.1.2 .


"RMS supports four record formats:

Fixed-length format
Variable-length format
Variable-length with fixed-length control field (VFC) format
Stream format
The fixed-length and variable-length record formats are supported for all 
three file organizations. The variable-length with fixed-length control 
field (VFC) record format is supported only for sequential and relative 
files."
