I want to implement the arithmetic sum of hexadecimal numbers. Their results are expressed in hexadecimal numbers without considering overflow bits. How can I achieve it?

Hi,

I'm not sure I understand the question...
Hexstrings and octetstrings cannot be added directly in TTCN-3, but they can be converted to integers, and their sum can be converted back.

For example:

var octetstring x1 := '1234'O;
var octetstring x2 := '00FF'O;
var octetstring y := int2oct(oct2int(x1) + oct2int(x2), lengthof(x1)); // result: '1333'O

Hope this helps.

Best regards,
Botond Baranyi
