Subject: Need Advice on Using CP/M Function 13
 
Of course, when changing disks one should always
do a ^C.  But sometimes I forget, and then if
I use my editor I get a R/O message when I try
to save the file (and of course lose my work).
 
As an experiment, I patched a CALL to CP/M Function 13
(Disk Reset) into the initialization routine for
the editor.  Only five bytes are added by that, and
it seems to work like a charm.
 
But that is so obvious a solution that I cannot
imagine that the authors of editors had not thought
of it.  Perhaps the did NOT include that for that may come nd bite me.
 
So my question: What, if anything, is wrong with
this approach?  Where are the gotchas?
 
Thanks,
 
Eric
