I am waiting for my HP48SX to arrive in the mail from the states. Will is take ages for me to figure out how to use it?

But it all depends on how much of it you plan to use. If you want to get into all those funky I/O, systems-type programming, and other un- documented things, then you're in for a long summer. One of the best times to expirement with the thing is when you first get it...you can't really lose any- thing since you haven't got anything in it in the first place. I still think that "playing" with a calculator can teach you more than just reading the man- ual cover-to-cover. When you're playing with it, you're either trying out the features that you'll really need/use or that interests you. That way you can quickly become accustomed to it and skip the B.S. till later. Over time, you'll eventually pick up on the more obscure features. The 48 has so many things you can do with it that you'll never be able to learn all of it at once. Do you have a computer? I've been with PC's since age 8 and I'm still learning new stuff about them. The important thing is to learn to use the things that you need right away. Getting your tools online quickly gets you your money's worth faster. ____________________ Choudet "Jake" Khuon U51034@UICVM.uic.edu "I refuse to include a profound, enlightening, or otherwise cute quotation."-Me

I've had mine 5 days now, of which I've had very little time to work with the HP48sx, and I'm able to use it and do simple programming - much due to reading examples posted here. Of course, I've been going without much sleep for 5 days, too (I'm about 1/3 of the way through the 1st (of two) user manuals. ------------------------------------------------------------------------------- stebbins@guiduk.enet.dec.com
