Hi Chris,
you define
Char CustNo [5];
and set
r.CustNo[5] = chrNull;
to terminate the string. But the string has a length of 5, so the indices are
0..4, not 0..5. You set the chrNull as the first character of the next field,
so it's overwritten in the next step. Use r.CustNo[4] = chrNull; etc instead.
Greetings
Helmut
