Hello, All.
Does anyone try to use it? I was on the www site, but i can't understand
japan language, so i can't understand what they are trying to say me.
BTW, that filesystem compatible with filesystem on OS/390? Can i read dasd
from OS/390 in future?
ps: i am not familiar with mainframe stuff very well. If you don't
understand this yet :)
WBR, Sergey
