[My first script with a loop - Why isn't it working?]

Yes thanks. I just realised it's the capital D.

 

Thanks for the link to the function.

[My first script with a loop - Why isn't it working?]

Hi. Can anyone tell me why my code gets a syntax error at the Do of the Do...While loop?

float wsquared(float w)   // return the square of the argument
{
    return w*w;
}
float thimblea=106.039;
float thimbleb=200.718;
string txt="";
float OldDist=900;
float newDist=900;
default
{
    attach(key id)
    {
        vector avpos=llGetPos();
        float posx=avpos.x;
        float posy=avpos.y;
        float oldDist=llSqrt(wsquared(llAbs(thimblea-posx))+wsquared(llAbs(thimbleb-posy))); //use pythagoras to work out the distance
        
        integer a=0;
        integer b=1000;
        Do
    {
            a++;
            string txt=" ";
        }while(a<b);
           
           
        }
}
