Do they come as PRG files? Are they large?

The best way would be to simply try this, wouldn't it? I believe that LOAD calls OPEN itself, so unless you want to jump directly into KERNAL code rather than via jump table (which is what you don't want to do!) then you will get I/O error #2 aka FILE OPEN  ERROR if you don't CLOSE upfront. But I am telling that off head so checking is the best way.

Again - I believe you can reuse the SETLFS/SETNAM but don't take my word. It's just a few lines. Check this and let us know too! ;-)
