group or queue. I use it quite a bit when using a queue in a listbox
where the sequence of the queue fields doesn't match the order that
show in the listbox. Something like
?List{PROPList:FieldNo,1} = WHERE(MyQueue,MyQueue.Name)
This way, if MyQueue.Name happens to be the 5th field in the queue, I
can still use it as the first column in the listbox. Does that make
sense?
WHAT() returns a reference to a field in a group or queue. By
obtaining this reference, you can write code that is somewhat generic
without having to hardcode the label of the actual field throughout
your code. Something like this:
MyRef ANY
Code
MyRef &= WHAT(MyFileRecord,5)
Now, anything that you do with MyRef is the same as if you had done it
to the 5th field in the record without having to know it's label. You
can write a bunch of code that uses MyRef.
