[JW Lua] FCPageTexts - Retrieve Item at a specific index

[Bruce Olson]

Hi Jari,

I’ve been poking around in the list archives and found this reply from you
in two messages to Charles:

-- The record location for certain types of data. I added that so it would 
-- be possible to see the storage location on existing instances of 
-- FCPageText, for example. ItemCmper would be the same as the value you 
-- send to FCPageText:SaveNew(). ItemInci is the 0-based "record index" 
-- within the ItemCmper.
-- In what scope? In the FCPageText scope, ItemCmper would be the page 
-- number and ItemInci would be the subrecord number for objects stored on 
-- that page:
-- http://www.finaletips.nu/frameworkref/class_____f_c_inci_other.html

This is getting me closer, but ItemCmper is the Page # only for single page
items. It seems to be set to 0 for page ranges. Is that right? So that leads
me to thinking that I should be using Load(<arguments>) to get a specific
one, but I haven't quite figured out what the syntax should be.

Bruce

Hi Jari,

I am trying to iterate through all of the Page Text items in order to either
update them or add them if they are missing in a document. This is in order
to give a standard look to all the charts I write for my big band. I think
what I should be using is GetItemAt, but am stuck trying to implement it.

My process is to first iterate through all of them and modify a table with a
flag to indicate that it exists by inserting an ID. I thought that ItemCmper
and ItemInci were what I should use, but was wondering if there is an easier
way.
