Let's head back to the line where the trouble occurs, which I presume 
you want to fix.

m55:r--;if(R[r]!=1)goto m55;

r gets decreased until R[r] = 1.

That needs to be fixed so that r doesn't go below 0, so we'll use a 
structure construct to help us understand more easily what's going on.

Is that right?

In that case, let's count down to 0 and break out when we're successful.

for (r; r>=0; r--) if (R[r]==0) break;

or

for (r; r>=0; r--)
   if (R[r]==1)
     break; // out of for loop
