Exactly.  Custom LDEFs like the one written for ListMaster provide a way 
to bundle up sequences of calls to MoveTo, LineTo, and DrawString, which 
collectively provide a behavior very similar to what LC does under the 
hood when you replicate field objects.

Of course it's much leaner, as just about anything in C is.  And the 
price you pay for that performance is many months of challenging coding.
