Dear everyone,

  I have a general question. In windows (XP/7), when the maple code becomes long (1000+ lines), when i type some character, it takes some time to see that character appearing in the screen. i.e. certain lag. In linux, there is no such problem.

  I tried two computers and a few versions of maple, always the same experience. Is anyone here have the similar issue and/or how to solve this lag problem?

Hello,

  Excuse me, I have a code

****

for i from 1 to 5 do
  f[i]:=i*2;
print(i,f[i]);
end do:

  In windows, the output is

Dear everyone,

  Hello,

  I have a question about how to get the power 'n' in an expression "(x+y)^n". For instance, I have a Maple code

******

eq1:=4*x^n*y^m+(x+y)^n+x^3;

f1:=map(t -> `if`(match(t = c*y^d, y, 's'), subs(s,d), NULL),
      convert(eq1, list));
f2:=map(t -> `if`(match(t = c*x^d, x, 's'), subs(s,d), NULL),
      convert(eq1, list));

Hello everyone,

  I have a file, e.g.'helloworld.txt'. It cotains

hello 3 5 7
world 1 2 6

 If I use

  L1:=readdata(`D:\helloworld.txt`,3):
print(L1);

 I just got a "[]"

How can I get the data from the file which has many word?

Thank you very much in advance
