 Nasal strings are always arrays of bytes (never characters: see the utf8 library if you want character-based equivalents of substr() et. al.). They can be indexed just like in C (although note that there is no nul termination -- get the length with size()):

-Note that there is currently no way to tell FlightGear to reload Nasal scripts from the global Nasal directory at runtime, so in order to see changes take effect, you will have to exit and restart FlightGear for the time being. Note that there are some workarounds available, see: [[Nasal_scripting_language#Loading.2Freloading_Nasal_code_without_re-starting_FlightGear|reloading Nasal code without re-starting FlightGear]].
-Also, note that as of 05/2009, Nasal in FlightGear does not yet support any form of dependency resolution. In other words, there's no "import", "require" or "include" directive - this is also why most code in FlightGear is wrapped inside a _setlistener() call instead, which in turn waits for a FlightGear signal before executing the code (see below for details).
