I have encountered a perhaps similar thing. I have recently switched from OS/2 to
WIN/NT. I have large datasets written pa SAS for OS/2 version 6.10. I have one set
which is also compressed by SAS. After swithing to WIN NT I ran CONVERT to change
from HPFS to NTFS. A month later I tried to use this dataset. When I tried
a message box popped up which said 'Unknown Exception' and an address.
After clicking OK on 4 or 5 message boxes sas finally crashed totally.
This thing happes both in batch and dm mode.
I can repeat it after rebooting. I have sent this particular dataset to sas tech sup.
On my other machine I run SAS for WIN-95. I have copied this dataset to that machine
using PKZIP (it is 61 meg big) and SAS for WIN-95 can use it ok. BUT!!!!
When I try to copy the same dataset back to NT it still crasches sas.
But when I first run a data set to uncompress it and then copy it to my NT machine I
can use it without any problems.
This message, Unknown Exception, have followed me since I installed TS040. In base,fsp,af.
