@nm Apart from the Maple Help pages I cited earlier, there is more:

In the Install.html file, in the section of starting Maple, subsection for the Command-line Interface (CLI), it points one to the readme.txt file in the Maple installation directory.

That readme.txt file has instructions (for a Linux install) about executing "maple" if the PATH contains it, or otherwise referencing it by its fully qualified location. It states,

"Starting:
    In a shell, type the command "/usr/local/maple2024/bin/maple".
    Substitute the appropriate directory name if you chose to install
    Maple 2024 to a location other than /usr/local/maple2024."

Also, Maple's installation and launching documents are clearly split by OS (Windows, Mac/OS X, Linux). Nowhere in the Linux sections does it suggest that you as normal user would launch using `cmaple`. Yes, several Maple things are different, between those OSes. That's why the document is so heavily split up by OS -- installation, license manager, launching, activation, network installation, etc; those sections are all split up by OS.

So, using the `maple` script is documented in the Help system. And it's also documented in the installation docs.

And your arguments about what `cmaple` on Linux should do if you fail to pass it the arguments that the `maple` script passes are not accurate. The world is more varied than just your small sphere of usage.

@nm cmaple is a compiled executable, and the `maple` and `xmaple` shell scripts call it (with set-up arguments).

The `maple` script has a Help page,  ?maple

Calling the `xmaple` script is like calling `maple -x`.

There is a description for "Command-line Version" on the Help page,
   ?versions

It says, "To access the Command-line version in Mac or Linux, use the maple command.  In Windows, use the cmaple command."

?interfaces pops up that ?versions as 2nd item in the Help Browser (it's an alias).

note: On Linux the bin/maple script is an intended front-end for invoking the cmaple executable. Ie. `maple` sets certain key variables, and then calls `cmaple ` with arguments. (Normally, one wouldn't call it directly on that platform.)

(I had not noticed that the OP was attempting to call `cmaple` directly. Sorry, my eyes saw what I was expecting. Vote up for phil2!)

On Windows, it's different.

@C_R Yes, the Classic GUI was shipped alongside the Java GUI for some releases.

@C_R Let's not call the old (Maple 2024 and earlier) Java GUI as "classic".

The term "Classic" has meant the non-Java pre-Maple8 GUI for a long time, including in Maplesoft's documentation. It'd be confusing to re-use the term.

Please forgive me for editing the word in your response.

The problematic part is actually split across two separate Execution Groups. The "end proc" is in the second one.

That fact is obscured because both have XML property view="presentation" (ie, the red chevons don't show, and F4 doesn't join them).

The simplest is to not try and Copy&Paste that.

I don't know exactly how you got it into that state.

Is there a subdirectory "afm" (with about 13 files in it) under your Maple 2025 installation?

Eg, on my Maple 2024.2,
    /usr/local/maple/maple2024/afm

Does it work in your Maple 2024?

Btw, from the Commandline Interface (CLI) one might do it as,
    plotsetup(cps, plotoutput="full_file_name.ps");
to get both the filename extension as well as a colored red curve. Also, the plot driver is slightly different wrt orientation default (portrait vs landscape) as well as curve thickness. That calling sequence seems to act the same in the GUI, regardless of whether "cps" is the plot-device or whether the filename extension is explicit in the supplied name.

Please either add closely related queries on this as addtitional details here (in a Comment, say), or use the Branch button at the bottom of this Question to form a new Question thread with cross-reference links that get added automatically.

Also, if possible, you could attach an example that produced the system of equations (that use, or for which you want to use) the SemiAlgebraic solver.

When using the Mapleprimes editor's green up-arrow to upload a file, the 2nd step can be "Insert Link", even if the alternative choice of inserting the whole document (inlined display) fails.

A workbook file (extension .maple) can be first zipped up (.zip) in the OS, since the uploader doesn't recognize the former.

Otherwise, you could explain precisely how uploading and attaching your Maple file is failing.

@Saalehorizontale Unfortunately (for me), that's not actually and explicitly what you wrote in your Question.

@Carl Love Thanks, I missed that.

I hazily recall seeing the real[i] selector mentioned somewhere, but now I can't find it.

@Carl Love It seems to me that it'd also be useful if the OP were to include the conditions 1 < y, y < 2 in his solve call (as well as those assigned to area)

@mmcdara A single call to the eliminate command provides this condition directly.

@C_R Your worksheet shows a result of NULL from the last statement, the call to solve.

@Scot Gould 

I edited my Reply above, to show an actual wrapping/replacement proc for this. Please let me know whether it works ok.

Have your examples of 1) and 2) been reported?

It's slightly confusing to me that you've chosen only this Question thread to mention earlier problems that you say are not rare. If they are not rare and causing problems for several people then why not post/report on them earlier?

(please report problems/hangs/etc.)
