I am an enthusiast, working with Mikrotik and ROS is my hobby. I have several scripts that update DNS records dynamically. Everything works fine, except that if the file is loaded into a variable, then I hit the variable limit of 64 KB (or so). How can I load data into a variable if the file size is more than 300kb. I would be very happy if it would be possible to use at least up to 1024kb of memory for a variable. I also have a small question, is it possible to somehow turn off some LED indicators, for example, system ones, without turning off all the others using all-led-off?
