Check out this little snip from Rohit Khare's "W* Effect Considered Harmful": One way to think of WML is as programming 3270 screens with a very simple BASIC. An application is delivered to the handset as a 'deck', which allocates a corresponding pool of storage space for variables. Individual 'cards' are executed on entry and exit to render the handset screen: they can fill in (shared) variables, rerender on external event notifications (e.g. call completed), and bind further actions to a small set of buttons. The display calls themselves are essentially character-cell oriented, with tab alignment and bold, italic, underline, big, and small fonts. Tables, frames, colors, and so on are not supported. Semantic HTML markup like <ADDRESS> must be stripped out. Even simple declarative HTML doesn't mean what it used to -- <P> no longer begins a new line. 'Graphics' support is intended mainly for optional icons in place of text menus; no clickable menu maps or such. WML is really a scripting language...
