The current J64 jmf script does not allow you to map greater tha 2 GB
files. Technically it is possible and there is some promise (by Eric)
that this will be fixed in the future. My workaround is that I split
the data in 2GB files and combine the data to large J array because
J64 can manipulate larger arrays. However I am also waiting that J
can provide a fix to this limitation.

I am trying to map some large text files. I am using WinXP 64 on a
quad-core zeon with 8GB of memory.
When I try to create a JMF file above about 2GB the createjmf_jmf_
verb "fails" meaning that it creates a JMF file but the size is incorrect.
I am pretty new to mapped files, so I can't determine if this is a
bug, or I am just missing something.
Can someone point me in the right direction?
Here is the output from the J console.
createjmf_jmf_ ('c:\temp\test1.jmf');1750000000
createjmf_jmf_ ('c:\temp\test2.jmf');2000000000
createjmf_jmf_ ('c:\temp\test3.jmf');2250000000
dir 'c:\temp'
test1.jmf 1750000568 29-May-08 14:39:01
test2.jmf 2000000568 29-May-08 14:32:48
test3.jmf 64 29-May-08 14:33:03
