strange grub output

[luofeiyu]

in my grub:
grub>set isofile="(hd0,msdos7)/tiger/debian.iso"
grub>$isofile
what i get is
unknow command '(hd0,msdos7)/tiger/d'

it's so strange thing ??

I get the same result. It appears the set command may be character-length limited. I tried various names and it always cut off at the same point.

Not sure what you are trying to do, but the ISO links in my signature line might help you.
