This is a LENO demo lecture, which is part of the LAML tutorial.

We have now started the real authoring process. We did this by M-x leno-insert-point, or from the LENO Emacs menu: ' Insert Point '

This is an item with a single subitem We made it with M-x leno-insert-items. The leno-insert-items prompts us for the number of items and the number of subitems It is also possible to make the item from the Emacs LENO menu, using 'Insert items' or 'Insert simple items'.

The concept programmatic authoring: By programmatic authoring we mean authoring of documents via use of programmaing programming expressions

In LENO we use programmatic authoring.

We will now make a page with a graphical image

Figure. The first image - the most basic form of the image clause. The first-image.gif file must be located in the graphics and graphics/small directories.

Figure. Another graphics example using the image clause. In this example we use a few attributes of the image mirror function.

LENO is often used for teaching material about programming. Therefore the source-program LENO element is important.

Program: The negate function. This function is really from the SchemeDoc part of the LAML tutorial.

Program: The fac function. This is the classical recursive edition of fac.

;; Calculate the factorial of n. ;; .parameter n An integer ;; .pre-condition The integer must be non-negative. ;; .returns n! (define (fac n) (if (= 0 n) 1 (* n (fac (- n 1)))))

Program: The fib function. This is the classical recursive edition of fib, which is very time consuming.
