    Doug Royer asked this sensible question about my recent posting-
    
    >1 question:
    >w = 90*(1-SGN............
    >What does SGN mean?
    
    =======================
    
    Sorry, Doug, I should have explained.
    
    SGN(y) is the SIGN function in many (perhaps all) implementations of BASIC.
    
    If y is positive then SGN(y) = +1
    If y is zero     then SGN(y) =  0
    If y is negative then SGN(y) = -1
    
    Hope that helps,
    
    George.
