That can be done as long as the file contains program data.  If the purpose
is to read the contents of a sequential file as text, loading "file,s" will
get it into memory but won't be a good way to read it!  (You can then examine
memory with a machine language monitor but the formatting won't be very good,
and you can come up with some screen code vs. character code and even ASCII
vs. PETSCII problems, depending on the format of the stores file and the way
the MLM displays memory locations.)

And if you try to load it and list it, every PETSCII capital in the file will
get expanded into whatever BASIC keyword uses that value as its token.

What David Williams brought up can be done, but I don't think it's useful for
the original poster's intentions.

(I've responded in this thread to two other people who share my first name,
and their last initials are my first two initials.  Curious.)
