I have started using my HP28 as an electronic checkbook and it has all
my checks and deposits in there so I can search through it etc.  The
problem is that I have a program which takes about 45 seconds when I
give it a list of 100 or so items but it takes days and days when I
give it a list of 200 items.  I have not really played with it much to
determine the actual times but its clear that something in the
calculator is quadratic if not exponential.

The particular thing I'm doing is I do a list-> to put the list onto
the stack and then I simply process the items one at a time with a for
loop.

So the question is can someone point out why this is not a good way to
do things and perhaps suggest a place where I can find out good and
bad programming practices to use with this beast.

Thanks
