Hi

Would it be possible to have the option to automatically reserve the precise string length?

At the moment FC defaults to 20 locations why not just analyse the length and reserve accordingly.

How would Flowcode know what length you need? You might append to strings, get data from external sources etc. If you know the size you can specify the required size yourself: String name[size]
(Being a C programmer I still declare string sizes one element larger than the number of characters for the terminating zero)

Hi Kesing,

Like I said an option to have it. To give this some context I am working on displaying scrolling message text on an LCD display, some of which needs to be joined together. It would have been nice to use the length$() command and then be able to amend the reserved buffer space if need be other than arbitrarily reserve a chunk arbitrarily

Matt,

All memory allocations are done at compile time, so the is no way to change them at runtime. And if you know the required size you can set it yourself in stead of the arbitrary size.
