bug report with prefix set[ ] & list[]

[compsystems]

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

Step by step to show in detail where the problem arises.

Step 1: please enter

PHP Code:

symb2poly( 3*x^2 -9 ) 


[enter] show on history view [3, 0, -9] // ok,
does not matter if the 'poly1' prefix is not displayed.

Step 2: then press
[up key] then [copy] (previous output) [enter] shows the true output expression, that is, with the poly1 prefix

PHP Code:

poly1[ 3, 0, -9 ] 


// ok

Since it is different list[ 3, 0, -9 ] to poly1[ 3, 0, -9 ] or set[ 3, 0, -9 ] when it is operated.
for example:

PHP Code:

[ 3, 0, -9 ] * [ 3, 0, -9 ] 


[enter] returns 90 // ok Interpreted as a dot product (vectors)

PHP Code:

poly1[ 3, 0, -9 ] * poly1[ 3 ,0, -9 ] 


[enter] returns poly1[ 9, 0, -54, 0, 81 ] // ok

PHP Code:

poly1[ 3, 0, -9 ]  .* poly1[ 3, 0, -9 ] 


[enter] returns poly1[ 9, 0, 81 ] // ok

in the most recent firmware version

Step 1: Enter

PHP Code:

solve( 3*x^2 -6*x -9 = 0, x ) 


[enter] returns [ -1, 3 ]

Step 2:
but [up key] then [copy] -1,3 this is a pair not a list, the containers [] are lost
-1,3 + 6 returns [ -1,9 ] // bug, because the container is not incorporated

in XCas shows on worksheet [ -1, 3 ] and with copy [ctrl+c] as list[ -1, 3 ] //ok

the prefix list[ ] must be preserved and can be displayed as [] or {} (it is indifferent on the history view), but the important thing is to keep the internal prefix when it is carried to the entry line




Another case, the information (entry) is also lost in sets.

Step 1: previous firmware (no beta). Enter

PHP Code:

set[ a, b ,c, a, c ] 


[enter] show on history view [ a, b ,c ] // ok

Step 2: then press
[up key][up key] (previous entry) then [copy] shows the true input expression, that is, with the prefix SET

PHP Code:

set[ a, b, c, a, c ] 


[enter] set[ a, b ,c ] // ok


Step 1: current firmware

PHP Code:

set[ a, b ,c ,a ,c ] 


[enter] show on history view [ a, b ,c ] // ok

Step 2:
[up key][up key](previous entry) then [copy]

PHP Code:

{a, b, c, a, c} 


[enter] { a, b, c, a, c } // bug this is not a set, because the prefix was lost and he no longer interprets it as a set


Please hpp-team recover the previous prefix operation set[] and list[], taking into account that if an operation returns a list, add the prefix list[] as in xCAS

Thanks
