change global variable during execution

[lidia]

I need to know if I can change the default value of global variables during execution. I Know I can change value in the front panel, before the execution, but I would like to do this during execution in order to save any change the global variable can have.
Thanks

You cannot change default values of controls or globals during execution. If you need to preserve the values between runs, write the data to a file (the config files are designed for this) and when the program executes again, read the files and set the values of the controls accordingly.
