You
can, but this isn't really a DarkBASIC question.

But you can use DarkBASIC a bit.

. You have to use HTML, JAVA or MSDOS to do this.
Oh, boy, this is going to take a LOT of explaining, but here goes. Firsly, you have to use the execute file command, something I picked up arounds here. If you want to make it look nice, you put in
sync on
sync rate 0
ccolor = RGB(0,0,0)
INK 0,ccolor
CLS
PRINT "Press any key to continue..."
WAIT KEY
PRINT "executing..."
execute file "C:\WINDOWS\DOSPRMPT.PIF","",""
END
(You can substitute the C:\WINDOWS\DOSPRMPT.PIF part for a premade program in MSDOS.) If you've never programmed in MSDOS then, a black box will come up and type in "start", then, with a little help from what comes up from the screen (if any) and some online tutorials you can get programming. If you have, then no probs.
Happy Programming.

In the deep world of programming, if you fail to prepare, you prepare to fail.
