counting up

[Steve]

I have been trying to write a small program the would start to count from on up keep going up until I stopped it I don't want it in time I just want it to count up and help on this would be great

[buff1]

Well if it's not to show the time that is seconds.. that makes it all the easier
10 k&=k&+1
locate 10,10
print k&;" ";
for j&=1 to 10
a$=inkey$
if a$<>"" then stop
next
goto 10

Let me give you some examples:

FOR I = 1 TO 100

NEXT I

Whatever is placed between the FOR and the NEXT lines will execute repeatedly; first it will execute with I being 1; then with I being 2, and so on until I = 100.

For instance you can simply do this:

FOR I = 1 TO 100
PRINT I
NEXT I

to display all the numbers from 1 to 100. (They may scroll off the screen but that is another matter and may be dealt with with things like LOCATE, adding a semicolon (;) or comma (,) after PRINT I, or using a delay such as SLEEP 1).

There is also

DO

LOOP

which is a simpler loop; if you want to count "forever" (Eventually the numbers become too big for QBasic to handle, but it will take a long time for that to happen) then you may place something like

I = I + 1

within, to increase the contents of I by 1 each time the loop repeats.

To interrupt the loop with a keypress, you may wish to test INKEY$ against the empty string (""). If it is not equal, then a key is being pressed. You may exit a FOR-loop with EXIT FOR and a DO-LOOP with EXIT DO.

If you want any more help, it would be helpful if you could show us what your program looks like so far.
