COMMENTS : 

1) 	AGE - there were infants in the population.
2)	3DEGTBA - some cases did fall in the 0-4 % burn area.
3)	paO2 to CbHg - 0 represents "NORMAL" and no reading was taken.
4)	Note that variables 6 9 11 13 21 22 23 are multiple variables.
	For example, avoid reading variable 9 as a single integer of 
	length 10 - you might get nonsense if the machine word size is
	insufficient.
