These programs will multiply together parameters one and two supplied to the program and pass the result back in parameter one.  The default is to pass the result back as a two decimal numeric field of length eleven (8 numerics the decimal point and two decimals).  The number of characters returned before the decimal point is always eight but you may alter the number of decimals by passing the value of 1 – 5 in parameter six. If you alter the number of decimals returned then the return value length will change accordingly.  The difference between COBTOT and COBTOTR is that COBTOTR will use rounding whilst COBTOT will just truncate to the correct number of decimals.
