Sebastian,
I had a similar problem with USRYIELD and usysuw. I changed this value PARAMETER ( NMXEBN = 600 ) to a large enough value for the size I wanted and recompiled the function. My results seem fine.
I too did not find any warning in the manual and people more familiar with FLUKA did not respond to my post warning me against it so I think its ok,
Lindley
