COMPILE XREF option

The XREF option of the COMPILE statement provides a variety of static data about an ABL procedure, including:

  • Other procedures that are RUN
  • Text strings that exist in the procedure
  • Code pages, include files, and shared variables used
  • Events published, subscribed, and unsubscribed to
  • Database tables accessed
  • Indexes used for a particular database query

The following example shows the XREF option output generated by executing execlog.p. (See Run-time diagnostics for sample code of execlog.p.)
