Problem: History to entry line [up]...[copy]
Hello

recent firmware

Quote:"HP Prime Graphing Calculator
Software Version: 2.0.0.13865 (2018 07 06)
Hardware Version: Emu
CAS Version: 1.4.9 6x
Serial Number: E43247C51117C96
Operating System: Windows 10
© 2018 HP Development Company, L.P."

/!\ the items 1,3, and 5 must be done manually [shift] [cas] (settings), the autosimplify xcas command has not yet been included in the hp-prime cas catalog, this is a problem because from the history view or program I can not control the output format, result unexpected outputs. Request hp-prime team, please include it in the next firmware version the autosimplify xcas cmd
Thanks

please follow the steps below to check the bugs

1: autosimplify(None); [enter] // set manually to simplify: none

2: answer:=domain((1/(x+1)),x); returns x≠1 // ok
[up] [copy] x<>1 // lost pretty print

2.1: [up][up] [copy]
answer=domain((1/(x+1)),x); // the symbol ( : ) is lost: [enter]
returns True=x<>-1 ?
[up] [copy]
equal(True,x<>-1) ?

3: autosimplify('regroup'); // set manually to simplify: minimum [enter]
4: answer:=domain((1/(x+1)),x); returns 1 // Why?

5: autosimplify('simplify'); [enter] // set manually to simplify: maximum
6: answer:=domain((1/(x+1)),x); returns 1 // Why?

7: a=b
[up] [copy]
equal(a,b) // lost pretty print

8: poly2symb(poly1[1,2,3])/poly2symb(poly1[4,5,6]) returns (x^2+2*x+3)/(4*x^2+5*x+6) // ok

9: Bug with Entry flag: set to textbook

(poly1[1,2,3])/(poly1[4,5,6]) returns (poly1[1,2,3])/(poly1[4,5,6]) // ok
[up][copy]

poly1*([1,2,3]/poly1)[4,5,6] ? [enter]

"Index outside range : 4, vector size is 3 Error: Invalid dimension" ?

poly1 is a reserved word, prefix of an array that means that the data type is a polynomial, it can not be interpreted as variable, that's the problem.

10: (x^3-6*x^2+11*x-6 | x=y) + (x^4-x^3-6*x^2+11*x-6)/x^6) :;
returns
"Done" // ok

but
[up]
nodisp( (x^3-6*x^2+11*x-6 | x=y) + (x^4-x^3-6*x^2+11*x-6)/x^6) ) [enter]
nodisp( (x^3....
lost nodisp xcas cmd, The command nodisp is used in xcas to not show the result or output, very useful when the output is very "large", another example M0:=ranm(50,50) [enter] [[-49,31,-68,39,82 ....
