Re: XML-INTO woes

[Scott Klement <rpg400-l@xxxxxxxxxxxxxxxx>]

Hi Peter,

XML-INTO will fill in only the elements that it found in the XML 
document.   The remaining elements in your array are undefined (point to 
adjacent memory) and you should not use them.  Using them would be "bad."

The number of elements that are passed to your %HANDLER is given to you 
in the 3rd parameter to your procedure.
