[Tutor] simple search and replace...

[Spencer Parker]

That was only a small example of a message...the message contains several
elements.  If I have the PID segment then I have OBR segment...an OBX, etc.
 So it would have to cycle through finding each element that is in the
message till the end.  I actually meant a list and not a
dictionary...terminology confusion in my head.
