Subject: ERAQ16 selective erase program available

ERAQ16 v1.6 - Selective erase program is now available on SIMTEL20.
ERAQ shows file names and separately asks confirmation on each, prior
to erasure.  This minimizes accidental erasures.  (If you still erase
a file you meant to keep you can easily restore it to normal by using
a program called "UNERA".  This assumes you have not overwritten any
part of it.  Every CP/M operator should have "UNERA.COM" for peace of
mind!  This program is patterned after the ERAQ function provided with
Digital Research's MP/M system.

Here is a list of the new files, followed by a short Modification &
Update List:

Filename                       Type     Bytes   Sectors     CRC

Directory MICRO:<CPM.DIRUTL>
ERAQ16.ASM.1                   ASCII    12012   94 =  5EH  DF52H
ERAQ16.COM.1                   COM       1024    8 =   8H  ADF2H
ERAQ16.HEX.1                   ASCII     2516   20 =  14H  671BH
ERAQ16.INF.1                   ASCII     2440   20 =  14H  5228H

04/06/84  Modified to display drive code with filename.
  v1.6                 Jim Dreher

12/21/83  Increased capacity to more than 256 files.  Used to have 
  v1.5    problems with large directories because file counters were
          only eight bits wide - now 16.  Made the "no files specified"
         error optional by conditional assembly.  Added "ASEG" directive
         and eliminated colons on equate lables to allow assembly by
         Macro-80.
                           Tony Newman (WB7FCN)

01/10/83  Modified to eliminate warm reboot when finished.  Was most
         annoying, for if not in 'A' drive rebooted both the current
  v1.4    drive and 'A' as well.  Reformatted, now assembles normally
         with ASM or MAC.  Standardized tab stops, some were missing.
         Included error message if no files specified for erasure.
                                       - Irv Hoff

04/16/82  Mask bit 7 for console output for memory-mapped video boards
which use the high bit for attribute info.

12/10/81  Added checks for $SYS and $RO attributes.

11/20/81  Added default to '*.*' if no input parameters.

11/08/81  Original program written by Thomas Hill.

The UNERA program mentioned above has been available from SIMTEL20 for
some time.  Here is a list of the UNERA files, for your convenience:

Filename                       Type     Bytes   Sectors     CRC

Directory MICRO:<CPM.DIRUTL>
UNERA20.ASM.1                  ASCII    17261  135 =  87H  54C6H
UNERA20.COM.1                  COM       1408   11 =   BH  29E4H
UNERA20.DOC.1                  ASCII     4760   38 =  26H  0E8CH
UNERA20.HEX.1                  ASCII     3440   27 =  1BH  D801H
UNERA20.HLP.1                  ASCII     4796   38 =  26H  EFD0H
