Start of Query Execution
The Start of Query Execution event point is to query execution what the Start of Process event point is to query setup. It executes once, at the start of query execution.
Immediately before this event point, APPX restores the copy of all record areas in memory that was saved immediately subsequent to executing the End of Process event point in query setup (see End of Process below). However, positions within files are not restored. For example, if you performed a READ on customer 10 before the End of Process, a READNEXT in Start of Query Execution accesses customer 1, not customer 11. To access customer 11 with READNEXT, you must first READ customer 10 in Start of Query Execution.
