SHELL SORT RETURNS SCR GARBLED

[andre drabs]

Hi,

Concerning sorts... there are some good sorting routines in PB...
I modified a sorting routine to sort files on disk, so that little
memory is not longuer a problem ... Why not give it a try ???
If interested in the disk-version, send me an email and i will
mail it to you..

hi,
if you sort as many files as i do, there is also a program you must try.
it is call rpsort. i have version 1.03. i can really say this program is
nothing but awesome. it sorts very very large files and fast.
did i say fast and no problems so far. i wish somebody had told me about
this product years ago. it is free. the author died some years ago and
his brother put the program in public domain, even the source can be had.
ROBERT PIRKO was the author and he deserves large caps for the reason.
of a job well done and i wanted to honor his efforts here.
paul purvis

the program can be found on the internet by doing a search.
good luck

Tom H, I think he's shelling out to the SORT.EXE included with
windows.

Tom B: Have you checked out ARRAY SORT in PB? That's a fast
little bugger and you won't have to shell out to get it.

Hmm. Save the screen first? Or write your own sort routine?

Yes, there is a reason. Just not worth explaining all the
background behind it.

It is just code to recreate the problem I am having.
I am converting from an old Visual Basic for DOS program.

The display works fine before the SHELL.

After the return from the SHELL the screen becomes unreadable.
Looks like the screen is displaying the graphics in text mode

The while statements are there just to display the results
of the problem.

The following seems to fix the problem,
but unfortuneately clears the screen.

Screen 0
Shell "SORT /+13 <CUST.DAT >CSRT.DAT"
Screen 11

What do you mean, "the screen comes back garbled"?

Is there a reason for switching to SCREEN 11? That's a VGA graphics
mode, and it doesn't look like you have any need for graphics. Maybe
your video adapter doesn't handle VGA graphics modes properly?

When I Run

SCREEN 11
CLS
PRINT "PLEASE WAIT"
K$ = ""
WHILE K$ = ""
K$ = INKEY$
WEND
LOCATE 16, 1 : Shell "SORT /+13 <CUST.DAT >CSRT.DAT"
PRINT "COMPLETED"
K$ = ""
WHILE K$ = ""
K$ = INKEY$
WEND

.
THE SCREEN COMES BACK GARBLED. I AM USING WINDOWS XP.
