copying problem

[qbasicking]

I was copying a BINARY file i had made bit-by-bit, but then I realized that using SHELL "copy..." was 5-10x faster, but now my screen says "1 File(s) Copied" does anybody know how to prevent this from happening, at the time I am just switching the video pages, but it seems like a bit of overkill

Forgive me if I'm wrong (I've quit using a QBasic almost 8 years ago) but i thing that using

Shell "COPY c:\filename.bin c:\Temp\Filename.bin > NULL"

will prevent DOS from actually printing anything on screen.

TIP: You can use any of the DOS standard device names to redirect the SCREENs outputs to any other port (COM1: COM2: LTP1: NULL or even another FILE)

Using the command Shell "DIR C:\*.* /s /b > C:\HDD.C"

will record all files in your C: and store them in the file HDD.C

Have fun & let me know what happens.

You must be thinking of redirecting stdout to the NIL: device, as in:

DIR >NIL:

See thread314-404524. The code seems to copy files somewhat faster than the DOS copy, without the overhead of shelling to the command interpreter.

Do no harm.​
