if..and..then question

[lake]

hi i have a w0 value and t changes as my programming runs and i and wondering if i can have 3 if's in one line of progrmming like
if w0=0 or 1 0r 3 and b0=2 then gosub...
or will i have to do it as three if's

oh and while ive got this post could someone tell me how to control the speed that it changes of
for b=0 to 9

line i need it to be the same speed all of the time and it has to be in a different subheading as i am running it in a dot matrix and it is the speed of a ball going along the screen so i carnt have a wait command or pause in it as it will slow the dot matrix effect and it wont appear to be on all of the time many thanks

You can put multiple AND and OR conditions in an IF-THEN but you have to play around to get it to work as expected if mixing AND and OR.

To change the rate of moving something within a loop, put a counter within the loop and only do something when the counter exceeds a particular value. You then need to rest the counter to zero to start again. This example updates a display every 10mS and moves a ball every 50mS, you'll have to adapt the idea to whatever you need ...<code><pre><font size=2 face='Courier'>Do
Gosub UpdateTheDisplay
Pause 10
counter = counter+1 % 5 ' 5 x 10mS = 50mS
If counter = 0 Then
Gosub MoveTheball
End If
Loop </font></pre></code>
