I went to a particular website where I downloaded Maple programs in .txt files.

If I open the files and cut and paste the .txt into a Maple worksheet,

a > is inserted at the start of every line. It would take forever to delete each of these

>'s from the start of each line in a program with 500 lines.  Someone suggested that I put the command

read C:\\filename.txt

into my Maple worksheet. But, this - and many variations, with and without single quotes, file extensions, etc. - does not work.

Any suggestions?

Both Mathematica and Maple have no procedure for stopping an out-of-control, non-terminating computation, except for pulling the plug on the comptuer. Whenever I give Maple a computation which is too big for it to handle, it not only does not return an answer, but it crashes my entire computer. It makes dragging up any other windows nearly impossible. There is no "stop" or "escape" key.

Absolutely amazing. Absolutely every single time I go to Maple to invert a matrix,

the syntax changes. Sometimes it can recognize M:=[[1,3],[2,5]] as a matrix. Then the next time it never will. It requires M:=Matrix([[1,3],[2,5]]); Sometimes it is MatrixInverse(A). Other times it is MatrixInverse[A]. Other times a matrix must be written as <<1,3>|<2,5>>. Sometimes the command is with(LinearAlgebra). Other times with(LinearAlgebra[Generic]). Some of these commands on in the Help menu. Other times they cannot be found.

I am trying to get my Maplet, at the url above, to return 2 times the number

the user enters for X. I want it to return it in the textbox I created.

The output textbox does not appear as I want it to.

Can one create applets in Maple like one can with Java?

Can one create an interactive dialog box, as simple as one can make it,

whereby one can click on a radio button among a finite set of options

and enter a number into a text field, and output another number?

If yes, then how?

Secondly, can one convert one's Maple program into Java for others to use,

who may not have Maple, if one wants to put it up onto the web?
