1) start cmaple.exe;

2) type "proc(x, x);", and watch Maple die;

3) Request a refund from Maplesoft.

I am using command-line Maple cmaple.exe, I have been trying several hours to type the correct several characters to create a lambda function (anonymous function), but Maple's documentation is only for people using the GUI and gives no hint how to translate the right-arrow symbol into ASCII.

What is the secret, undocumented sequence of ASCII characters for defining an anonymous function via the command-line interface? (Why not document it in the user-manual, for those of who can't stand Maple's bad GUI?)

Trying to read the docs, I find a lot of information in section that appear closed, and I'm supposed to move my hand from the keyboard to the mouse to bounce a laser off my desk to click triangles on the screen to make the information I need visible. Sometimes when I click a triangle, it opens the section and lets me read the docs. Other times I click a triangle, it does nothing, so I click again, and eventually it works. This process is unpleasant. Is there any way predictable way to view the docs, or just click triangles and hope?

New user. Start a new "Worksheet Mode". Type "3" and press Enter. Maple evaluates it to 3. Decide I want to add a section-heading above the original first line. Head into the docs and emerge several hours later still not having found any way to add a section-heading above the original first line. How did I lose so many hours of time on something so basic? Where was this routine task documented?
