Null is an unfortunate word because it means several things to different programmers. C/ASCII programmers think of Null as being x'00' - a string terminator. SQL programmers think of NULL as a column attribute meaning 'no value assigned.' And then there is a group who confuse x'00' with x'40'... In your example, I would probably define bMsgCode as varying. Then it only contains '12' and nothing after it. Translating it to ASCII is another issue. You probably don't really want to send a string of x'00' to the other side; perhaps only one at the end of the '12'. If that is the case, I would simply concatenate x'00' to the end of bMsgCode. --buck
