Re: new here and stuck on loading and unloading a piece of code repeatedly without memory errors

[Guido ter Horst <g.terhorst@...>]

The idea of the program is to use loadfile to load the functions as entries in the table currentPage. what I don't understand is that when I empty 'currentPage' by assigning NIL, and then loading another set of functions into the table 'currentPage', how is it possible that when I do that several times the program will crash?

The only thing I can think of is that 'currentPage' is set to nil and loaded with data again from within a function that is part of the currently available functions within 'currentPage', and it is that which is causing some problems

any idea's?.

You might want to ask whomever provided you the software.

lcd.drawText is not a standard Lua function.

The standard Lua functions are documented here:

What happens on a "crash"?  Can you view a stack trace?
