3. TFRCTL (Transfer Control) is a control language command
which 'hands off' execution to the program listed as the
receiving program.
Once this happens, the original program drops from the call
stack and can not be returned to.
Hence, ANY code following a TFRCTL is wholly skipped,
unless some type of flow control is designed in the program
which could possible skip the TFRCTL.
