; ERAQ16 v1.6 - Selective erase program. Shows file names and separately
; asks confirmation on each, prior to erasure. This minimizes ac-
; cidental 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.
;
; NOTE: The title shown above is difficult to type for normal use. As
; these programs are shown on various listings, the only way you
; know if you have the latest is by checking the version number
; Once you have the program, you might consider renaming it for
; local use, keeping the original title on a master copy so it
; could be transferred intact to other users. You might, for in-
; stance, rename it to "ER.COM". This is very easy to type and
; would not accidently call up the normal ERA function should you
; you intend to type ERAQ and miss the last character (difficult
; to type under the best of circumstances.)

; Modification & Update List:
;
; 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.
