Preallocation via repeat is a good solution, thanks.

Actually, I have run across this problem in a "real" program, though I
didn't know it at the time.  The program dealt with several little
creatures scurrying around in a virtual environment, 500*500*3 4 byte
spaces stored in memory.  Each creature's behavior was controled by a
function into which I fed a sequence repesenting the 101*101*3 area around
it (50 spaces in each direction).  Each 4 byte space was translated into
6-8 integers which were appended onto the subseqence representing that
space.  I had abandoned the project because it was just too slow, but after
a few changes to the code to avoid appending, it's beginning to look viable.

thanks,
Isaac
