Your expectation would be wrong.

File opens without RMS use QIO to open a file.

I will state that the RMS PARSE routine is used to parse a filename.  But that 
has nothing to do with an OPEN.  I'd also argue that the routine really is 
misnamed because it has uses outside RMS.

If you don't believe me, I'll post some code.
