Download the luaforwindows5.1.exe file and follow it, write a script file as follows, and run it, the result is unexpected, unexpec symbol near'&'. This means there is a grammatical error. Not even with the latest version of 5.1.5. Finally, I saw the instructions in the lua5.1 manual:

2.5.1-Arithmetic Operators

2.5.2-Relational Operators

There is no bitwise operators at all, which means that lua5.1 cannot perform bit operations.

Later, I checked the lua5.3 manual and found that bitwise operators,&, |, ~ and, OR, XOR operations all exist.
