EFF(FILE,CODE,EDT) ; returns effective date and status for code/modifier
 ; Input:
 ;    FILE = file number  REQUIRED
 ;           80 = ICD DX
 ;           80.1 = ICD O/P
 ;    CODE = ICD CODE ien  REQUIRED
 ;    EDT = date to check (FileMan format) REQUIRED
 ;
 ; Output:  STATUS^Inactivation Date^Activation Date
 ;          where STATUS = 1 = active
 ;                         0 = inactive  
 ;          Activation Date = date code became active

NUM(Y) ; convert ICD to $A() of alpha _ numeric portion
 ; Input:  Y - ICD code
 ; Output:  'plussed' value for ICD OP code,
 ;          numeric for ICD based on $A of 1st character (alpha)
 ;          concatenated with the remainder of the ICD DX code
 ;
 ;      **This does not convert to ien**
 ;
 ;  This converts to a numeric that may be used for range sorting
 ;
 ; A few ICD DX codes start with "E", "M", or "V" - use ascii
 ; Remaining ICD DX codes will use 10 as a prefix - insuring DX > OP
 ; All ICD OP codes match dd.d, dd.dd, or dd.ddd
 ;     where 'd' is a digit; e.g. "V83.89"=8683.89 and "008.8"=10008.8
