terminal view to the main screen (history view) cmd - compsystems - 10-31-2018 10:50 PM

Hello, users and developer group of the famous hp-prime calculator
Sorry for my technical english.

In the following program

PHP Code:

#cas
    prg00( ):=
    begin
        local X, Y;
        assume(X, symbol); // elimina valor de X para asumirla como símbolo
        assume(Y, symbol); // elimina valor de Y para asumirla como símbolo
        PRINT; // Limpiar pantalla
        print( "Hello Mathematical World" ); // Escribir "Hola  mundo matemático "
        wait( 2 ); // Esperar 2 segundos
        print( 'X²/3 - Y²/5 = 1'  );
        wait( 2 );
        PRINT; 
        return “Done”;
    end;
#end 

I have a question

How to return from the terminal view to the main screen (history view)?

for example in xCAS there is the DispHome() command

Thanks

Code:

Syntax:

STARTVIEW(ViewNumber[,Redraw])

Starts a view of the current app. Redraw, is optional; if Redraw, is true (non 0), it will force a refresh for the view.

The view numbers are as follows:

0=Symbolic

1=Plot

2=Numeric

3=Symbolic Setup

4=Plot Setup

5=Numeric Setup

6=App Info

7=Views key

And NO... the Prime does not need a

Code:

STARTVIEWHOME()

command

Hello Erwin

Why?
On the contrary, it is necessary, because the screen is small, it is a way of dividing the views

Quote:If ViewNumber is negative, the following global views are used:
-1=Home Screen
-2=Modes
-3=Memory Manager
-4=App Library
-5=Matrix Catalog
-6=List Catalog
-7=Program Catalog
-8=Note Catalog
?=CAS view

STARTVIEW( -1, 1 ); // return to HOME VIEW
Iseems that it does not work, please try the following code

PHP Code:

#cas
    prg00( ):=
    begin
        local X, Y;
        assume(X, symbol); // Remove the value of X to assume it as a symbol
        assume(Y, symbol); // Remove the value of Y to assume it as a symbol
        PRINT; // clear screen.
        print( "Hello Mathematical world" ); 
        wait( 2 ); // Wait 2 seconds
        print( 'X²/3 - Y²/5 = 1'  );
        wait( 2 );
        PRINT; 
        STARTVIEW( -1, 1 ); // return to HOME VIEW
        return “Done”;
    end;
#end 

The equivalent in xcas is

PHP Code:

prg00():={
        local X, Y;
        assume(X, symbol); // Remove the value of X to assume it as a symbol
        assume(Y, symbol); // Remove the value of Y to assume it as a symbol                
          DispG;  // Initialize terminal view and graphic view.
        ClrIO // clear screen.
        print( "Hello Mathematical world." ); 
        WAIT( 2 ); // Wait 2 seconds
        printf( X²/3 - Y²/5 = 1  ); // Print in 2D readable printing (Pretty Print)

        WAIT( 2 );
        ClrIO; 
        DispHome // return to HOME VIEW
        return “Done”;
}:; 

And it works well, that is to say it is executed from the main view that in xcas is called worksheet then it opens the terminal view and at the end it returns to the terminal view, without having to press the key [esc]
