@alarmgv12 @crafty oh, now that I think of it I don't know how it works with command blocks but if you can use some kind of conversion of a char to say its ASCII value you can create a number that will consist of all the ASCII values, or you don't even need ASCII, you might just be able to make sort of a Base64 of your own with every letter from a-z, A-Z and '_'. That would be easy af to do with code, but I didn't think of it in a vanilla command-block way

The issue with command blocks is that there is no way for a player to enter any value other than an integer/number, the player would have to do the conversion making it useless.
