I'm rather new to programming the Amiga, but have been looking at the
interrupt system.

One approach that seems reasonable would be to send a message to the 
timer.device asking it to send you a message in ten minutes (600 secs).
Arrange that the reply port that it sends to generates a software 
interrupt of priority higher than your program (so that it preempts
it), and this swi can delete the message, ask that another message
be sent in ten minutes, and write out your intermediate data.  Of
course, you'd have to make sure that a swi can do things like delete
messages, send messages, open files, etc.

How's that sound?
