I wouldn't be surprised if VMS provided some sort of indexed
random-access file structure that supported inserting records.
OSes of that era tended to be big on things like that, since
they were all about Serious Data Processing.

But it probably wouldn't have let you insert data into the
middle of a sequential file without explicitly moving
everything that came after it.
