Most modern computer languages run with the executable instructions in a "pure code" section, which is set to be NOT writeable by the program. This avoids a LOT of simple mistakes and REALLY hard to find program crashes. This is true of MS, Linux/Unix and the VMS program environment that I have used for about 40 years. I think you have to go back to maybe Windows 95 or RT-11 to not have that protection.
