In Release 8.2, if a user interrupts a DATA step, cancels the submitted
statements and the data set named on the DATA statement already exists
then the data set is incorrectly replaced with a partial data set ( i.e.
as many observations as have been generated when the step is
cancelled). This is true for both permanent and temporary SAS data
sets.  The following notes will be generated in the log:

  NOTE: The data step has been abnormally terminated.
  NOTE: The data set dset has X observations and Y variables.

Where X represents the number of observations and Y represents the
number of variables.

Prior to Release 8.2, if a user interrupts and cancels a DATA step and
the data set named on the DATA statement already exists, it is not
replaced. The following notes will be generated in the log:

  NOTE: The data step has been abnormally terminated.
  NOTE: The SAS System stopped processing this step due to attention.
  WARNING: The data set dset may be incomplete.  When this step was
           stopped there were X observations and Y variables.
  WARNING: Data set dset was not replaced because this step was stopped.


To prevent the incorrect replacement of a permanent data set, specify
the NOREPLACE option. There is no circumvention for temporary data
sets.
