Hi,
I am currently in the process of writing a program in Maple to add points of
an elliptic curve over a finite field, and I am having difficulty determining
how to organize my output as a table. I have tried using the array command
but was unsuccessful as it only recognizes the last entry in the loop. Any
help would be most appreciated.
Thank you

From this message it's very hard to figure out what your actual difficulty
is. In what way does it only recognize the last entry in the loop? The
usual way to put entries into either an array or table inside a loop
would be something like:
> for i from ... to ... do
...
T[i] := ...;
od;
This will automatically set up T as a table. If you want it to be an
array, set up the array first, something like
> T:= array(1..1000);
for i from ... to ... do
...
T[i] := ...;
od;

Subject: programming a table
To:
A table is the most general random access data structure in Maple. It
will be created as soon as you assign to an indexed symbol. You may use
nearly everything as index expresssion (of course also simple numbers if
desired). The following statements show the creation of the table
My_Table containing some nonsense. The final statement eval(My_Table);
shows its contents and you see that there is not only the final entrance
present. Could it be that you positioned your assignment statement
behind the terminating clause of the loop (end do or od in previous
versions)?
< for i from -2 by 3 to 4 do
> for j in [red,green,blue] do
> for k in [10,100,x^2] do
> My_Table[i,j,k]:=i+j+k
> end do
> end do
> end do;
> eval(My_Table);
All the best Jurgen
