$Sequence( "hello" , randomize("world") )
@
@newTrial( "world" ,
@    newButton("world", "Earth")
@        .print()
@        .wait()
@)
@newTrial( "world" ,
@    newButton("world", "Moon")
@        .print()
@        .wait()
@)
@newTrial( "world" ,
@    newButton("world", "Mars")
@        .print()
@        .wait()
@)
@
@newTrial( "hello" ,
@    newButton("world", "Hello...")
@        .print()
@        .wait()
@)

• Will run the trial labeled hello first, even though it is defined below the world ones, and then will run all three trials labeled world in a random order.
