copy oldfile==>newfile

Code:

FUNCTION CopyUnderProgramControl (newfile as string, oldfile as string) AS INTEGER
 IF DIR$(newFile)> ""  THEN
   KILL NewFile
 END IF
 hNewFile  = FREEFILE
 OPEN newFile for binary as hNewFile
 hOldFile = FREEFILE
 OPEN oldFile for binary  AS hOldFile
 BlockSize =   8192 
 nBlock    =   LOF(hOldFile) \ BlockSize
 Oddbytes  =   LOF (hOldFile) MOD BlockSize

 FOR block=1 to nBlock
   GET$ hOldFile,BlockSize, S
   PUT$ hNewfile,S
 NEXT block
 IF OddBytes THEN
   GET$ hOldFile,oddbytes, s
   PUT$ hNewFile, S
 END IF
 CLOSE hOldFile, hNewFile

I knew it was MS-DOS when I replied, Don. .. but in all honesty I had to really reach back in Ye Olde Graye Matter to remember how to do this working within the memory limitations.

But FWIW, posted code will work under Windows, too.

**Michael Mattias** · 30 Dec 2006, 09:16 AM

And just to clarify...

The "flicker" is, as you suspected, a byproduct of using SHELL ("batchfile.bat"). Because SHELL causes another process to start (assuming you are running on a Windows O/S) and you have no real control over the task-switching, it's just one more process which has to share processor time with everything else.

Even when I wrote a lot of MS-DOS code (and I did write a lot of it), I avoided SHELL or EXEC (RUN?) if there was any way to get the job done from within my program. That was mostly because I'm a control freak, but a nice byproduct when I got to Windows was the reduction of 'flicker' and/or "flashing console" when a particular thing needed doing.

**Buck Huffman** · 30 Dec 2006, 08:39 PM

from the PBDOS reference manual:

NAME statement
--------------------
Purpose
NAME renames a file or a directory (like the DOS REN command).

Syntax
NAME filespec1 AS filespec2

Remarks
Filespec1 and filespec2 are string expressions conforming to
DOS path and file naming conventions. NAME gives the file or
directory represented by filespec1 the name filespec2. Since
filespec2 can contain a path name, it's possible to move a
file(but not a directory) from one directory to another. You
can't move from one disk to another.

If filespec1 does not exist, run time error 53 ("File not
found") occurs. If filespec2 already exists, run time error
75("Path/File access error") occurs.

Differences
The DOS REN command can only rename files, not directories.

Example
INPUT "Enter the name of the file to rename: ".OldName$
INPUT "Enter the new name of the file: ",NewName$
PRINT OldName$,NewName$
NAME OldName$ AS NewName$
END

Is that anything like what you were looking for?

An exercise with Mr. Michael's code.

  DIM StrLenght AS LOCAL INTEGER

  IF Msg = "" THEN
    PRINT "All done!"
  ELSE
    StrLenght = LEN(Msg)

    PRINT UCASE$(LEFT$(Msg,Position))

Code:

CASE 53: ErrorType = "File not found ...
CASE 55: ErrorType = "File already open.. 
...

Using Windows compilers,the ERROR$ intrinsic function would be a really handy thing..
