Does there exist a way in Maple that you can detect a change in a text file without having
to constantly having to call the readdata which keep the command prompt busy in Maple.
For example if you have a txt file that is constantly updating it self with new data
I want the matrix in Maple to be updated dynamically by adding the new data.
Is this possible ?

How can I tell Maple to read all txt files in a specified folder ?
The names of each txt files are different ( I dont know the names )

I want to display the output from printf ( columns as seen below ) in a MathContainer (embedded component) . How ?

seq(printf("%20a  %10a  %10a  %10a  %10a  %10a  \n", i, i^2, i^3, i^4, i^5, rt[i]), i = 1 .. 10);

How can I assign all diagonal elements to 1 for a matrix ?

I want to find a way that which results in that all variables in a procedure becomes local

ie  X:=proc() local All

I find it tedious having to specify all the local variables individually 

ie  X:=proc() local A,B,C,w,e,r,t,y,u,ui,io,w,,u,i,o.....eternity
