Some changes have been made to COPY since the manual was written.  
Comparison of dates with Existence testing ON has been changed to 
use the Creation date when no Modified date exists, and print 
"Undated" when neither exists, yet both source and destination 
disks support file date stamping.  Additionally, the /X option 
has been re-defined, and a new /R option has been added to 
Version 1.4.  Please replace Paragraph 4.1.2.9 on page 55 of your 
ZSDOS manual with the following two paragraphs describing the new 
options.


4.1.2.9.1  ERASE SOURCE FILE AFTER COPY.

When you want to "move" a file from one area to another, the "X" 
option may be used.  This option causes a file or group of files 
to be copied in the manner described by the default or specified 
options, but after the copy and optional verify, the source file 
or files are erased.  You will be notified that the file has been 
erased by the status "(X)" being printed on your console.  To 
minimize the possibility of deleting a good file when errors 
exist in the copy, the Verify option should always be active, 
either by default, or specified.  When Verify is active, any 
errors detected will disable the "X" option for that file so that 
a good source file will not be deleted.  The "X" option has no 
configurable value, and is always assumed to be "Off" requiring 
the option in the command line list to be effective.


4.1.2.9.2  COPY ONLY FILES WHICH EXIST (REPLACE).

Occasionally, you may wish to update selected files to a destina- 
tion in a simpler manner than naming each file, or using the 
Inspect option.  The "R" (Replace) option, when active, tells 
COPY to transfer only files which exist on the destination direc- 
tory.  If the Archive option (A) is added in conjunction with the 
Replace option, only files which have not been archived, AND 
already exist on the destination will be archived.  It should be 
noted that the No Replacement (N) option is incompatible with 
both the Replace and Archive options, and is disabled when either 
"R" or "A" are active.
