Global properties and functions
Properties: none.
Functions:
akey
band, bnot, bor, bxor, lshift, rshift
eval
exit
Keys
mmode
msgbox
print
prompt
Notes:
1. Functions band, bnot, bor, bxor, lshift и rshift (bitwise operations)
are global aliases of the same-named functions of bit64 library.
(see LuaFAR manual).
2. Functions akey and mmode, when called from within function condition of a macro,
return false.
3. For uniformity sake, all the above functions (except the bitwise ones)
are duplicated in table mf, for example: eval и mf.eval reference
the same function.
