Hi Tomasz,

quick / small question reg. FASMG lengthof operator :
if I do e.g.

-> i get LEN = 2, despite value obviously being 1-byte only
.. and similar behavior - i.e. byte lentgh +1 - for any value with sign bit set: 0x80, 0x9000, ...


Is this this intended / on purpose ? ... so need to reimplement some 'byte length' operator then ?

The LENGHTOF is only defined for string values, and when you use it with another kind of value, it is implicitly converted to string first, so "lengthof 0xFF" is the same as "lengthof string 0xFF".
If you test this: you can see that the value is converted into a 2-byte string. That's because fasmg always treats the numbers as sign-extended, little endian with arbitrary length (so it's the highest bit of the last byte that needs to be equal to the sign): Also if you convert a string back into a number, it is interpreted as a sign-extended value.
