Entry / command line bug - BruceH - 11-22-2018 10:49 PM
Latest ROM...
In CAS mode, assign a value to a variable using STO▶︎ or :=, e.g.
3▶︎f or f:=3
In either case, the History shows this as:
f:=3
Now select this in History, Copy to the command line and it changes to
f=3
Note that the colon has been lost and you now have an equality instead of an assignment.

SIMPLE ANSWER: Methinks that either you or a program you loaded was messing around with Python and the index base got changed. Typing this into CAS:
index:=1
will reset things back to normal. And don't mess with Python any more... or trust programs with Python syntax in them.
BETTER ANSWER: Forthcoming from somebody who knows which Python commands are capable of messing up Prime like this.

I checked, the 3▶︎f and 3=>f, f:=3 and all copy to the command line f:=3.

I did indeed run someone else's Python program, thanks for the heads-up.
RE: Entry / command line bug - retoa - 11-27-2018 01:09 PM
I have the same problem, but I never ran python programs nor any other.
I can not insert an equation in CAS:
a=2 will be taken as a:=2
x=2*x^2+3 as x:=2*x^2+3 so the Prime tries to assign 2*x^2+3 to x itself and i get an error, recursive definition, which is true with :=
Same problem on 2 different Prime end one windows virtual calculator.
I tried with index:=1 but it did not bring any difference.
Here the display, note that I did not write the ' ' around index

RE: Entry / command line bug - retoa - 11-27-2018 11:08 PM
The problem disappears if I set Simplify to "none" in CAS Settings.
This means that if I set Simplify to "minimal" I can not work on equations that begin with a single letter left of the equal sign, like a=3x+5
Is this supposed to be the right behavior or is it a bug ?
