question about LiggghtsCommand dictionary

As noted in the online documentation:
//////////////////////////////////////////////////////////
liggghtsCommandModels
(
execute
);
executeProps0
{
command
(
run
$couplingInterval
);
runFirst switch1;
runLast switch2;
runEveryCouplingStep switch3;
runEveryWriteStep switch4;
verbose;
}
///////////////////////////////////////////////////////////////////
command inside the executeProps0{ } needs "Each word in a new line, numbers and symbols need special treatment", my question is if I really need a number (say 0.2) in the command, how can I realize it?
I tried the #include, but it dosenot work.
Any hint is appreciated. Thanks.
