The Load-function in this case simple refers to a two-dimensional array:
array[Cmper][Inci]
This is used in many classes (e.g. Expressions) or similar in 
articulations (array[NoteEntryNumber][Inci]).
Cmper is usually the measure number, the page number or whatever makes 
sense in the context. Sometimes you need to try what Cmper refers to. 
It's not always that clear in the documentation. But if you think about 
what makes sense, you will find out.

Inci starts with 0 and each item has an increasing number.
Note: I am not sure, but if IIRC it's also possible that there are leaps 
in the inci numbering (i.e. Inci 0, Inci 1, Inci 3) if items were 
deleted or if the document is corrupt, especially on expressions.

IIRC pagetexts use the array[PageNumber][Inci], so loading means:
PageText:Load(PageNumber,ItemNumberOnThatPage)

Best,
Jan
