No change

I would expect these results because str = "a" probably makes a 2 byte
field, the "a" and "\0". I would expect "num" not to work because it is
defined as a number (num = 97). Therefore Lua would make it a float long (8
bytes?) value with mantissa and exponent.


>ff = 0x0C or ff = string.char(0x0C) ?

ff is defined as 0x0C, i.e. "local ff = 0x0C".
