Actually my machine also said BAD CARD DATA and erased the contents
of PORT 0. Nothing was in it that was important.
I never thought of checking memory space but when I did WOW only 6057
bytes left!!!!!!!!!!!!! And I only had about 7k of programs in the
machine before trying to download MLDL. Yet the machine said that
the MLDL had been erased from the PORT so I should have had ~23K.
So as was said by someone on this list (sorry I lost the file and your
name) I backed up to a friends 48 hit the dreaded ON-A-F and RESTOREd
the backup. Abracdabra!! 23K left.....
I'm confused???????????
Incedentally my setup Version D ROM
No Cards
USER mode on.
The only other machine code in my machine is Bill Wickes ASC-> and ->ASC
and MODESBROWSER.

I made the same experience after a crash caused by MLDL. I think the BAD CARD DATA is due to the self modifieing code Jan wrote. The machine just didn't have the time to correct the checksum. I suppose it thinks the whole port is corrupted, so it doesn't touch it. I assume the user is given a last chance to save things in main memory, and then she should do an ON-A-F. Or she should remove the bad card, if the port number wasn't 0. That't better then doing the reset automatically in this situation. And what if the offending card is ROM ? >So as was said by someone on this list (sorry I lost the file and your >name) I backed up to a friends 48 hit the dreaded ON-A-F and RESTOREd >the backup.

On a related note (that is, related to having the 48 trash all of Port 0 on occasion), I was tinkering with a library stored in Port 0 (I believe I was attempting to change a message in Bill Wickes' Jekyll/Hyde library), and did not have the correct checksum for this object. The 48 said, BAD CARD DATA, and wiped the entire port....all menu labels were blank. On a whim, I tried PURGEing the offending library, and, voila, the rest of the Port 0 objects returned. So if you suspect you know which object is causing the problem, try PURGEing it even though it doesn't show up in the LIBRARY menu. Stephen J Thomas sjthomas@cup.portal.com
