Hi, Guys Scanning through the forum it appears that (using V4B 8.3+) it is OK to define global variables in the Starter Server (in the sub Process_Globals) as it will not be removed by the OS whilst the App is running, Question - is that correct? Also, would I be safe to store global variables...

Hi, I am trying to write XOR encoding/decoding for B4X (I need to use it as a light weight and fast encoding/decoding cross plateforme solution with B4I, B4A, B4J and Lazarus/FPC). I know XOR is not the best/strongest encryption solution but it should be ok for my needs). The following code...
