solution to the problem of pre-assigned variables Z1:=3+4*i in HOME mode
It is known that the logic of the HP-PRIME HOME mode inherit from HP38/39/40 calcs of pre-assigning variables to objects,

A, B… Z for reals,
Z0, … Z9 for complex,
L0, L1… L9 for lists,
M0, M1… M9 for vectors or matrices etc.,

affect the logic of the programs in CAS, many students do not know why their source code fails to execute it.

The solution is to use A ... Z 0...9 characters and numbers UNICODE and non-ASCII A ... Z, 0, ..., 9

0: FF10
..
9: FF19
A: FF21
Z: FF3A

A≠A
L0≠L0
M0≠M0

This involves break free the characters A..Z 0...9 ASCII and their combinations as for example L0, M0 to store any object

This is done by the Classpad calculator, in the following image you can see that the variable in italics is different from the normal variable

AB=A*B ≠ AB ≠ A*B

the unicodefont of the hp-prime
ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789
ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789are similar to the ASCII
ABCDEFGHIJKLMNOPWQRSTUVWXYZ0123456789, please hpp_team modify as it appears in this forum, making the characters visualized for example in italics and/or bold

abcdefghijklmnopqrstuvwxyz

Good Idea? +1
