No, GetHEAD and SetHEAD won't work either, since QPC doesn't allow me
to open a channel to the file to be renamed (I suppose if it did, I
wouldn't need to alter the filenames in the first place.
Interestingly, if you try to open a file such as OPEN
#3,'flp1_'&chr$(0)&'test' it creates a file called 'flp1__test' (the
CHR$ 0 is replaced by an underscore) but the reverse is not true - a
filename containing a NUL seems to be protected in some way. DIR will
list it, but that's as far as you'll get.
OK, a challenge to you and other resourceful guys out there, short of
suing a disk editor, or going back to a level 1 QL, any other
ingenious ways around this?
