Sorry, there are few bugs in my MV.PAS: when copying file, need
Reset(fi,1); and Rewrite(fo,1); - otherwise Turbo Pascal uses default
record size 128; need check IoResult after almost every operation (at
least after the Reset(fi,1); because it is not true what Borland's
manual states as explanation what causes $I- compiler option: "An I/O
error thus does not cause the program to stop, but suspends any further
I/O until the standard function IOresult is called." - in fact further
I/O is not suspended and Rewrite creates output file after Reset which
failed because file was not present; additionally Rename to different
device causes error 'Not same device' even if renamed file don't exist
- final result is empty file created on target device if source don't
exist...). Additionally, it is valuable to use GetFTime/SetFTime to
set target file date/time to be same as source...
All these problems if trying COPY using the MV.PAS, disable possibility
to copy (don't $Define COPY) and can use the program without any problem.
