RE: A83: Apps, adding to current menues


Once again the Direct G returns to the conversation and is still lost.  I
have no background in ASM and I was hoping to come here for help. Anyway
Dan You wrote something I had on my calculator befor Mirage Cleared the
ram when I tried to graph something.  I haven't had the time to download
the new Mirage But it better not get in the way of my Calc homework like
the old one does or someone will have alot of debugging to do. anyway as I
was saying I am here for the good of those plus users without a clue like
most of my friends. I'd would specifically like to add the following
features:
-3-d graphs(I have that program that comes on the graphlink CD but It is
dirt slow and is quite hard to master figuring that I myself haven't
gotten it to graph half the stuff I wanted it to.)Allong with these graphs
you have to be able to rotate the graph and especially get a birds eye
view(I know I'm asking alot but I'm just letting all of you in on my
dreams.)
-A better Equation Solver more like the one the 85's have, Not every
equation =0
-better derivation and to higher degrees and if possible symbolic
derivation

Thas'd all I could think of now and I'm sure I'll think of more
later.  but that's what I'm trying to do can anyone out there help me and
I'm talking to you DAn and Robby and Joe W. and all you great programers.

Peace Out,
The Direct G
