(48G) GCD: Greatest Common Divisor

[Albert Chan]

Hi, Thomas Klemm

My guess is « WHILE REPEAT END » cannot compile, and had to store internally as « WHILE REPEAT *PASS* END ».
*PASS* is just a placeholder. Above thus similar to Python code, while 1: pass

To minimize program byte count, common keywords use less storage.
*PASS* probably is pretty rare for a (internal) keyword, which does nothing ...
