Last Frame Keyword
L switch alternative, once an item with a frame in it with this keyword in it is displayed the job stops. Not a required switch anymore and only useful for having multiple ending points within an item.
Note, use of <SkipDisplay> in a last
frame item prior to version 188.8.131.52 of DMDX would result in the job being aborted and any data not being saved,
this is now rectified.
