With Maple 2025.2 on Windows

I do not get the multiplication dots also when I replace Pi by x. 

Can you upload the worksheet using . This makes it easier for others to reproduce the error.

@nm 

First time I see this (maybe because I do not use Physics very often). Rerunning Download ex1_jan_18_2026.mw

gives a warning.

Maple does not restart propperly... a second restart is required.

However, removing timelimit from your code does not show the warning after restart.

Have we (unintended) come across two implementation weaknesses or is this a combined effect?

@nm 

Occasionally I encounter output of a command that depends on the use history of Maple (not necessarily the use of the command). The output is not wrong but different. In cases were  forget(command) is not effective I use map(forget, [anames()]) to the reset other remember tables of functions (which I do not know) that are called during the execution the command.

This works sometimes. However I am not sure whether really all remember tables that could influence Maple output are reset. The kernel for example could remember results that cannot be forgotten this way. Hence the question. My intention is not to permanently disable.

Ideally forget could offer an option that not only forgets the remember tables of a command but also all other remember  tables encountered during the execution of the command. This would be more specific with less computational effort than forgetting all.

@nm 

Why there are no better debugging tools? I suppose that Maplesoft has better debugging tools for internal use. The fact that the old tool is still available, but no better one, could be because Maplesoft want to make it difficult for other companies to reengineer Maple algorithms. The openess of Maple (which I appreciate) might be one of the reasons why Maple lost its leading position. 
I remember a time when Mathematica was inferior in many aspects. Maybe they copied to catch-up. 

I am not using the debugger very often but sometimes I use showstat on procedures to be debugged in a separate worksheet for better oversight without the need to scroll.

@Sim123 

What you are showing is new. I would also contact support.

I would keep it. Several users had firewall issues recently. 

In my case my IP was blocked but I could access other Maplesoft urls. 

It would be helpfull to post a screenshot of the firewall message.

@acer 

Yes, I misunderstood.

The 1D plaintext came from converting 2D Input to 1D with the intend to see what was behind this error message

Concering the use of atomic, I either do something wrong or my setting performs differently.

I might come back here but need some time for tests.

As always, thank you for your time!

@acer

I do not want to change the default setting as you have shown with:

Typesetting:-Settings(useprime = false)

To make sure that I understand your answer correctly. By single right quotes you do not mean

The key (on my keyboard) next to the tilde key "~" (for which I have to do Alt+tilde followed by spacebar) shows a single right quote but it does not print in Maple. In MS-Word for example it prints; see here: "´". I can paste this symbol from Word to Maple and make it work in Math-1D but not in Math-2D

Using Alt+´ followed by spacebar would indeed be easier than the keyboard acrobatics I have mentionned above. Right now I cannot make single right quotes appear and work in Math-2D.

By the way: Omitting the name quotes leads to an unpleasant overlap (yellow below) in the input and the output

whereas namequotes are visible in the input when I use atomic variables from the favorite palette.

With right single quotes from the favorites it looks better. That is already an improvement.

@GunnerMunk 

I cannot reproduce the results with capital M. Could you send a Maple file (with the green arrow) and tell us if you have used any special unit settings (like with(Units[Simple]))

From ?solve,details

The solve command returns all solutions for polynomial equations. In general for transcendental equations, the solve command returns only one solution, but does not set _SolutionsMayBeLost to true. To force the solve command to return the entire set of solutions for all inverse transcendental functions, provide the solve option allsolutions = true

I would have expected one solution without allsolutions.

This one also does not return a solution

solve(sin(x)/x)

@janhardo 

Expr := Int(1 / (sqrt(-alpha*l^2 + 1) * %sqrt(-alpha*l^2 * (x + 1)/2 + 1)), alpha = 0 .. z);
Expr = value(Expr);

All by hand...not very practical in larger expressions
Thank you

@janhardo 

Yes Il-subs is the normal form I would like to achieve. 

So far I could only achieve it by hand and making sqrt inert to prevent automatic simplification

@nm 

I was about to ask if I am the only one in need of this functionality. Since MMA has it, there must be a need.
Thanks for checking

@janhardo

The first one in this particular example. It is closer to the normalized form of first incomplete elliptic integral.

Only for information:
Ideally after further manipulation I would like the get the following displayed

However automatic simplification kicks in and prevents this by automatically factoring out 2.
