The COPY command is flaky and has always been that way.
Even using a defined PATH in a batch file.
That is how you got some corrupt files of Abasic that I sent you.
There is an option in MYMENU2+(Mybasic pgm) that allows
you to backup your HD. Program creates a batch file with
defined paths for each file. Then from Mdos it backs up the
entire HD using the copy command. When these files are
restored sometimes the progress info on the screen indicates
the file was not restored(copy command), but when you check, 
the file is there.
The Abasic corrupt files was the first time that I had seen a
file become corrupt when it was backed up(Copy command)
