Allo
Hopefully someone can help. I'm sending the following code to my RCX when I
click on a vb menu item:
Private Sub mnuFiveHundred_Click()
SetDatalog 500
lego.SetVar 12, CON, 500
End Sub
ie setting variable 12 to 500 in immediate mode. Variable 12 is then used by a
downloaded program to set a number of program loops. The variable works fine
up to 255 and does the required number of loops. But 256 or greater, doesn't
work. I thought variables could go up to 32k. Could it be something in VB?
What's wrong???
thanks
Mike

| (...) The variables are 16 bit signed (-32768 to 32767), but the loop counter is only an 8 bit unsigned (0 to 255). When you set the loop counter from a variable it ignores the high bits and truncates. Dave Baum (25 years ago, 12-Dec-99, to lugnet.robotics)
