BITMAPCHUNKINMEMORY is used during code generation to decide whether or not bitmap chunks can be
constructed in memory. It is faster to construct bitmap chunks in memory but if there are a lot of bitmaps,
the indexed property or properties have very low selectivity or the index values are large then STORE errors
can be encountered. If BITMAPCHUNKINMEMORY is 1 then bitmap chunks are constructed in memory by
%ConstructIndices. Otherwise, bitmap chunks are constructed using process-private globals. The default is 0,
meaning that bitmap chunks are built using process-private globals.
Files the indices for all objects whose ID is in the range defined by pStartId and pEndId.
If pEndId is null then it defaults to pStartId. If pStartId is null then the
range is empty and no filing will occur.
If lockExtent is true then an extent lock will be acquired before the indices
are built. If the lock cannot be acquired then an error is returned. The lock is released
after the index filing is completed.
Returns a %Status value indicating success or failure.
