2 :: Can you explain about component Buffer?

When you open any page in a component, the system retrieves all of the data records for the entire component and stores them in one set of record buffers, organized by scroll level and then by page level. This component buffer consists of rows of buffer fields that hold data for the various records that are associated with page controls, including the primary records; related display records, derived work records, and translate table records.
PeopleCode frequently must refer to data in the Component Buffer, that is, the area in memory that stores data for the currently active component.
There are two methods of specifying a piece of data in the Component Buffer from within PeopleCode:
-------- Contextual references, which refer to data relative to the location of the currently executing PeopleCode program.
-------- References using scroll path syntax, which provide a complete, or absolute, path through the Component Buffer to the referenced component.

The component buffer contain current active component data it is temporary memory area .

3 :: Tell me What is the diff between component level peoplecode and record level peoplecode?

Record Level peoplecode:
The peoplecode written on the Recoed level Peoplecode will affect all the Components in which that particular record is used, and if we want to execute the record peoplecode for particular Component then we would need to add following code in before existing peoplecode

If %component = component.<Component Name> [statement_list_1]
[Else
[statement_list_2]]
End-If;

Component Level Peoplecode:
The component level Peoplecode works only for that particular component and if any record in the component is referenced by component level peoplecode then it would not effect any other component where same record is used as it was doing in above case.

Sequence: first Record level peoplecode will fire and then Component level peoplecode.

As far as sequence is concerned
