What solve handles is the option real, which passes e.g. to SolveTools:-Polynomial as the option domain = real:

> trace(SolveTools:-Polynomial):
> solve(x^4-16,x,real);
memory used=1.0MB, alloc=38.3MB, time=0.14
{--> enter SolveTools:-Polynomial:-ModuleApply, args = x^2+4, x, domain = real
..
<-- exit SolveTools:-Polynomial:-Quadratic (now in SolveTools:-Polynomial:-
ModuleApply) = []}
<-- exit SolveTools:-Polynomial:-ModuleApply (now in PolynomialSimple) = []}
                                     2, -2

As I see it, this option real is subdocumented (it occurs combined with parametric in ?solve,parametric).

I agree, the MathML specifications for the mi element allow for multiple character identifiers. So, presumably, the #mi construct that you show should be OK in TypeMK.

What could be done along this line is using separated execution blocks for each pair of commands like:

restart:
read "sheet3.mpl";
1  3   1  2     1  2      2                2                    3
- x  + - x  y - - x  z + y  x - 2 z y x + z  x + ln(x + z - y) y 
3      2        2                                                

                      2                        2
   - 3 ln(x + z - y) y  z + 3 ln(x + z - y) y z 

                    3
   - ln(x + z - y) z 

Yet, clearly, this "combined" session approach falls short of your objective. In particular as restart does not clear everything (read ?restart). Meaning that the results of this combined session might be different from those of independent sessions (and there are even more subtle "cache" effects resulting from the design of the Standard GUI).

A previous question is whether they are all still in this site. Very frequently I find posts that have disappeared...I keep a local copy of relevant threads and typically I search first locally.

@casperyc 

You will find many more! I keep finding many bugs per day...

Worse, quite frequently posts disappear from this site...I keep a local copy of the relevant threads and frequently search there.

@casperyc 

Well, for x+y you do not really need typeset output. The prettyprinted 2D output of the CLI is fine for me, except for very complicated/long output. You should try and see. The Standard GUI is not designed for such batch usage. For instance, export to PDF may not be possible programmatically. 

In ?backslash there is a line in the table characters:

a bell (alert) BEL

However, it has never worked for me... Perhaps a system call to an executable playing a sound may do it.

@Carl Love 

If relevant, I keep a copy of that thread in my archive.

@Carl Love 

Sure, typographically, epsilon corresponds to `ϵ`. It seems that this is a somewhat involved historical issue (e.g. see here).

@Mac Dude 

I quote Jacques here: "there really are now 2 Maple languages, 1d and 2d, which are (unfortunately?) extremely similar." Indeed, they have different parsers, different syntax and different error messages. In particular yes, in 2-D Maple something like De(t,z):=... does define a function (by a disambiguation box).

It is not spam if receiving email notifications is an option set in the account by the user. And any change in the operation of the site due to a change in local legislation should be properly notified by the administration as the user community is multinational.

@Carl Love 

Here, Linux 32-bit, the original code works in Maple 16 Standard GUI (and later) but yields the font error in the CLI and Classic.

@Preben Alsholm 

This is a regression bug affecting diverse expressions. It has been reported time ago.

@acer 

Do you mean no longer being possible to save into .m format?
