Some improvements in the lists set)

[compsystems]

Hello

1: The set union operation in uppercase is of functional type and in lowercase is an infix operation, but when placed in the history it is also shown as functional. Infix must follow in infixed form

UNION(set[1,1,2],set[3,3,4]) Enter
UNION(set[1,1,2],set[3,3,4]) set[1,2,3,4]

set[1,1,2] union set[3,3,4] Enter
union (set[1,1,2], set[3,3,4]) set[1,2,3,4]

2: Very long lists are shown endpoints, but more elements should be shown.
L_1 = set[1,2,3,4,5,6,7,8,9,10,11,…,∞] Enter set[1,2,3,4,5,6,7,8,9,10,11,…,∞]
L_2 = REVERSE(-L_1) Enter set[-∞,-…,-11,-10,-9,-8,-7,-6,-5,-4,-3,-2,-1]

(L_2 union {0}) union L_1 Enter
union (union (L_2,{0}),L_1) [-∞, .... ,∞]

3: The hp prime cuts the set[] prefix to just [], this causes loss of information detail, a solution is to change the square brackets to similar symbols in order to detect the type of data.

set[] -> []
best
set[] -> 【 】
or
set[] ->〔 〕or 〖 〗or 〘 〙
