     If the file actually contains a program in *tokenized* form, it
is fairly easy to change the filetype to PRG.  It's not 18,1 that you have
to change, though.  What you have to do is change the first byte in the
directory entry for the file.  A SEQ file will have $81 here.  Change this
to $82, and you have a PRG file.

     If the SEQ file does *not* contain a tokenized program, then you have
to use a different approach.  It involves re-directing BASIC's input
vector to the open disk file.  Sorry, but I can't tell you how it's done...
I no longer have the equipment.
