TI68K tiv200 Versus HPPrime Calcs - Terminal View - Symbolic Algebraic Printing

[compsystems]

Use of PRINT command on the terminal view for symbolic algebraic printing


Is required a new PRINT command PrintAlg(expr) or same, to print algebraic expressions in CAS mode. Display symbolic algebraic expressions is difficult in a single line and more when they are extensive.

PrintALG(expr) be used in a program that returns n symbolic outputs for viewing history outside (Terminal View)

I Agree with that!

I made the same request a couple of days ago here in this forum, TIM said that the terminal window is for the moment a single line thing. I guess all we can do is wait and keep asking HP to implement this feature in future OS's.

Since this is just a terminal, this might require another kind of treatment? like with the Grobs / SCROLL / VIEW in the 50g?

GraphObj or PictOBj But with

0 →GraphObject = no pretty print (1D or linear)
1 →GraphObject = pretty print (2D small font )
2 →GraphObject = pretty print (2D medium font )
3 →GraphObject = pretty print (2D large font )

'x^3-2*x^2+1*x-1' 0 →GROB
'x^3-2*x^2+1*x-1' 1 →GROB
'x^3-2*x^2+1*x-1' 2 →GROB
