I'm not a QBASIC Guru, but I've been programming in PowerBASIC for DOS
(which is kind of "improved QBASIC" ) for several years.

In order to emulate access to a so called BASIC "random access" file,
in Euphoria you basically (no pun intended) have to use a combination of
seek() and get_bytes() for reading or seek() and puts() for writing.
DOS or Windows doesn't matter.

A famous BASIC guru is Ethan Winer. The old 'bible' for DOS BASIC
programming, his book "BASIC Techniques and Utilities*, is now available
on the web at no charge:
   http://www.ethanwiner.com/

"winer.zip" contains plain text files and program source code as
separate files, "ethan.zip" contains the book in PDF form.
See chapter 6 for "random access" files.
