10.1 Hello world ¶

HALT

Will render a template without any external symbols and terminate execution immediately.

10.2 Handling menus and inputs ¶

MOUT to_foo 0
MOUT to_bar 1
MOUT upup 2
HALT
INCMP foo 0
INCMP bar 1
INCMP _ 2

Create three menu items, resolving the menu symbols to_foo, to_bar and upup respectively to translated text and pairing with the selectors.

Yield for client input. Then attempt to match input to selectors:

• if selector is 0, execute node foo.
• if selector is 1, execute node bar.
• if selector is 2, execute previous node in stack.

• Menu batch version

DOWN foo 0 to_foo
DOWN bar 1 to_bar
UP 2 upup

10.3 Signal flow control ¶

LOAD foo 1
CATCH bar 8 1
MOVE baz

If loading the external symbol foo sets the flag 8, then immediately move to bar.

Otherwise, move to baz.

10.4 Multiple pages ¶

LOAD foo 0
MNEXT to_fwd 11 
MPREV to_back 22
HALT
INCMP > 11
INCMP < 22

Load external symbol foo as a sink.

If content spans multiple pages, resolve to_fwd and to_back as labels for lateral navigation options in the menu.

Also handle the lateral navigation inputs.

• Menu batch version

LOAD foo 0
NEXT 11 to_fwd
PREVIOUS 22 to_back

10.5 Multi-page menus ¶

MSINK
MNEXT to_fwd 11 
MPREV to_back 22
MOUT inky 0
MOUT pinky 1
MOUT blinky 2
MOUT clyde 3
MOUT tinkywinky 4
MOUT dipsy 5
MOUT lala 6
MOUT pu 7
HALT
INCMP foo 0
INCMP foo 1
INCMP foo 2
INCMP foo 3
INCMP foo 4
INCMP foo 5
INCMP foo 6
INCMP bar 7

Enable splitting menu over several pages, and route all valid inputs to the foo node, except for 7 which is routed to the bar node.

• Menu batch version

MSINK
MNEXT to_fwd 11 
MPREV to_back 22
DOWN foo 0 inky
DOWN foo 1 pinky
DOWN foo 2 blinky
DOWN foo 3 clyde
DOWN foo 4 tinkywinky
DOWN foo 5 dipsy
DOWN foo 6 lala
DOWN bar 7 pu

10.6 Default input handler ¶

MOUT to_foo 0
HALT
INCMP foo 0
INCMP bar *

If input is 0, route to the foo. Any other input will route to the bar node.
