A shorter version would read: | |||
<syntaxhighlight lang="php"> | |||
var waypoint = {number:1,altitude:2,distance:3,angle:4,length:5,ID:6,bearing:7}; | |||
var new_waypoint = func {return {parents:[waypoint] };} | |||
var NUM_ELEMENTS = 5; | |||
var waypoints = []; | |||
setsize(waypoints, NUM_ELEMENTS); | |||
forindex(var i; NUM_ELEMENTS-1) | |||
waypoints[i] = new_waypoint(); | |||
</syntaxhighlight> | </syntaxhighlight> | ||
