I prefer a straw color background instead of the white.  I think the reason the background can't be changed is one of the reasons the dark mode doesn't exist, because they both stem from the same area that requires adjusting.  

Easily enough to workaround.  You just have to do all your calculations in an inserted table and change the cell color.  

As for maplesoft looking here for changes, I believe for some things they do.  But if changes do not occur from here then submit a software change request, and if years later it still doesn't happen - it's either too difficult, not important enough change to deal with at the moment or they haven't alloted available resources.  I would expect it would eventually get looked at.  

I found a couple of links, a few more would be good. 

Fracture propogation in the internal pressurized vessel https://www.maplesoft.com/applications/Preview.aspx?id=35194
Beam Analysis  https://www.maplesoft.com/Applications/Detail.aspx?id=3729

In fact it might have been a beam analysis application.  

In 2d math mode, you mean document mode? 

So it seems you only just want to find and replace just the subscripts?   Because it finds all occassions of the value 4, supscripts, superscripts, integers if just searching the value.  Probably could be fixed in a maple update for 2-d math. 

Oh, I've found it's just the layout,

I need to make sure the equation is not in the numerator of the parital differential operator. 

@Preben Alsholm I agree, do not change the name.

I think in the past I  had considered that as well.  

But as Carl suggested, additional search terms offer better results.  I mean just using maple you're always likely to get the Torono Maple leaf's and or maple trees or syrup.

It also depends on your analytics.  As you select more relevant maple articles to you, your search results will return more favorable sites.

If your search terms include some kind of Math, it generally responds with a maple code related page.  Adding mapleprimes, maplesoft to your search helps as well.

I use Firefox, but I find Edge works much better on Maplesoft.com.

The only difficulty I find, is trying to find specific threads in mapleprimes using google.  I usually have to think of alternate key words, and that could be because the searches are limited to the "tags" chosen by the poster.

**edit added ** If, and that's a VERY big if, Maple were to change it's name, I wouldn't see it deviating too much.  Even if it was changed it's not going to help finding all the past articles tagged with the original Maple name.  That aside if it became necessary to change the name I would suggest "MapleM", the M  to relate to Maplesoft and Mathematics, otherwise I'd rather like to keep the name Maple.

@acer Fair enough.

Otherwise we could move the condition inside the procedure.

c := [10, 20, 30];
change := proc(i, b)
  if b in c then b*i;
   else print("2nd variable expects:",c);
  end if;
end proc;

change(19, 56);
             "2nd variable expects", [10, 20, 30]

@acer do we need to specify identical?  It works without it but maybe there's a case where it needs to be used?

@Kitonum Thanks!  That's another good way. 

Oh!  It looks like idendtical is not needed.  I just needed to change the structure, but I was close.

change:=proc(a::integer,b::{10,20,30})
  a*b;
end proc:

Thanks dharr and nm!

@mmcdara ok great!  Thanks for that

@gkokovidis Thanks!

@acer Thanks! 

@dharr That will work.  Thanks!
