Loops

[Brendan]

Hi I am pretty new to QBasic and have made a couple of small proggies but i am doing a loop and it is running to fast what i want to know is if there is a way to slow it down?

TIA

There alot of ways to pause a loof like the SLEEP command. this command stops the whole program until a key is pressed or you can inenter this line

for num=1 to 10000
next

this makes qb count up to 10000 until it can keep going. you can also change the number to somethin smaller of larger

There at least 4 ways to slow down a looping program

Use TIMER, this is a good method for pausing or slowing down a program to intervals of around a quarter of a second.

SLEEP, a method of pausing a program for a whole number of seconds. Useful when displaying "splash" screens.

Do nothing loops, loops that simply count to a number then exit. This is not generally a good programming practice, but is an option. When using this method the results vary from computer to computer, but it is easy to implement.

WAIT, a method of introducing a very small delay into a program. The &H3DA, 8 part waits for a screen refresh.

Youcan see how each of these is implimented at members.lycos.co.uk/brisray/qbasic/qdelay.htm

A bit of self advetising I know, but it's easier to see the code there than for me to put the whole thing here.

Thanks guys!!!

Or try using quickbasic extended it has trace that slows down the program run. It also makes exe files out of your bas files. I downloaded if free off the web.
