*==============================================================================
Notes for WARNINGS:

    - Changes have been made for version 10.1B for the 'READ FILE (-4)' which
      performs read prior record operations for a text file. The changes
      were made to resolve unexpected behaviors when the text file contained
      deleted records.

*==============================================================================
The following files have been changed as noted:

-------------------------------------------------------------------------------
SUNDM

    - All additions and corrections applied to the 10.1B PLBWIN runtime for
      PL/B IO have been applied to the Data Manager. See the release notes for 
      PL/B for details.

    - Corrected problems that would give indeterminate behaviors and data
      when performing READ FILE (-4) (i.e. read prior ) operations when the
      data file contained deleted records. The indeterminate behaviors
      included skipping records and/or hanging while repeatedly reading the
      same record over and over. The unexpected behaviors could exist both
      with and without use of FILTER(s).
