  AppendedPageCount: Integer;
end;

Unit

HPDFDoc

Fields

Field	Purpose
`SourceCount`	Number of entries in the `Sources` array passed to `AssembleCollatedPages`
`SourceOpenCount`	Total number of source document opens performed whilst walking the collation rounds
`SourceReopenCount`	Opens of a source that had been opened before and had been closed again by the least-recently-used eviction
`PeakOpenFileCount`	Maximum number of source documents open at the same time; bounded by the `MaxOpenFiles` parameter
`AppendedPageCount`	Pages appended into the target document across every source

Usage notes

The assembler keeps at most MaxOpenFiles sources open and closes the least recently used one, so SourceReopenCount grows whenever the limit forces repeated reopening
Compare AppendedPageCount with the sum of the requested page ranges to confirm every planned page was appended
All counters are zeroed at the start of the assembly run and remain zero when Sources is empty
