We had the press file Tiffany.Press written on a floppy.  When we tried to (INFILE ''{FLOPPY}TIFFANY.PRESS), we got an error ARG NOT LP': NIL.'
This was from a \DTESTFAIL inside \SFLOPPY.OPENHUGEFILE, at PC 117.  The file shows on the DIR listing as having 206 pages.'

We discovered that the problem was that we were trying to get a file off of a floppy in a system in which we had previously done FLOPPY.MODE(SYSOUT) to save a sysout.'
When we did FLOPPY.MODE(PILOT), the error disappeared and everything worked fine.'
It is still a bug that the the floppy code gives the user a totally incomprehensible message in this situation, instead of informing him that he has the wrong floppy mode--or better still, flipping the floppy mode to be whatever is good for the floppy that is in there.  When the floppy is reading, why can''t it look at the disk and figure out what kind of mode it has.  And if the mode is wrong, why is it that it can get at the directory without any problem?'
It also seems reasonable to me to have the floppy revert to its base mode (PILOT) after it has finished writing a sysout and the disk has been removed and replaced.'
P.S.  You might want to inform 1100 support about the cause of this LP error; perhaps it should be noted in the release message as a known problem with this release.'
