    From Morris [11/24/04]

   To increase my understanding of programming in XY4, I am interested to know what the codes
below mean and how are some of them are produced - namely those involved in searching. The
Customization Guide does not seem to explain many of the items below as it is very much based on
Xy3.

What is the proper use of (;*;), Sometimes it is used at the end of a line - is this altogether
necessary to compile a workable program in Xy4.
