If expecting that increasing happens often why not doing it for bulks of 50 new, possible entries (or so)?

How does does one write that down in Maple?

names ... a neat way !

Any example what you have in mind?

For example if you have identities for Gamma functions in rational arguments then Maple is not unlikely to fail.

Same for numerics, if one expression is quite 'simple' while the other uses error prone (but mathematical correct) representations

I am afraid: no. And it is easy, just a bit strange :-)

Just type in 1 + 2 + ... at a command line. Maple will sum it immediately.

May be someone can come up with some frontend voodoo ...

I would not use procedures that way, since you return symbols (and I would
at least feed them to the procedure). 

And I do not see, why you need a proc: If you want to solve a system of
equations just use 'solve', see the help pages ?solve for some examples.

Also you should be aware what you do, if you write `x=3` (this is also
a symbol), perhaps you get what you want to see by 

  'x' = x;
                                x = -3

Note that ' and ` or ´ have different meanings.

If you use lprint also note that this suppresses pretty presentation for
results (you can enforce that by setting the print modus as well). Mostly
there is no need for that.

BTW: x is 3 makes no sense for Maple, see the command ?is.

The last: avoid || if you are learning, for concatenating the newer way
is cat, like cat(z,3) giving z3.


Generally I would suggest, that you step through some pages of a Maple
introduction, as it seems you have some basic problems handling it, just
do it and that will avoid frustrating and false learning.

If the task is quite simple then you may write it down as such :-)

Ok: not all implicite functions allow what you want.

Consider a circle plot([cos(t),sin(t),t=-Pi..Pi]) and recognize, that you may have 0 or 1 or 2 real solutions for y, depending on x.
