You're pretending that you don't know about the foo="bar" options on the
CRTL open/fopen/creat calls.  Yes, it's all via RMS, but you can tell it
to do or not do certain things. And the feature logicals, of course, but
it might be dinnertime in your time zone and I wouldn't want to give you
indigestion :-).

But from BASIC, yes, I think you have to write wrappers around the CRTL
functions and then call them from BASIC, or at least that's what I did
the one time I had to write stream files from BASIC.
