This optional parameter allows the user to specify that the collection
 operation should pick up from where it was last stopped.   The recovery
 will work only if the collection data file was not left in a corrupted
 state (this can be detected by the utility).

 The operation may have stopped due to a system reboot, due to the
 process being stopped, or due to the user pressing CTRL/C or CTRL/Y.

 This parameter may not be used in conjunction with any other parameter.
 Any parameters that were in effect from the original COLLECT command will
 remain in effect.

 Example:  COLLECT CONFIG_01_23_90.DAT RECOVER
