problem in attempt to write a FAT file
by Peter Easthope 01 Oct '02

Oberoners, Can anyone explain this phenomenon in PC Native 23.06.2002 and 24.08.2002 running on an old 486 DX? If there is no explanation at hand, can anyone replicate it at least? The FAT file system is mounted with this statement in Oberon.Text. { FileSystem.Mount C FatFS IDE0#01 ~ } Successive attempts to write a DOS file alternately fail and work with the following trap. Regards, Peter E.
