N for reading records without locking it. but, make sure
that you are not doing any updation in the DB file as
updation needs locking the record.This operator extender is
applicable for all the READ operations

H for Half Adjust
E for Error detection
D for Date format
P for Padded blanks

eg: MOVE(P) 'RAM' A 20

'RAM' WILL BE IN RIGHT END AND PADDED BLANKS WILL BE IN
LEADING SPACE

Answer / shalini

There are 4 operation extenders N,E,H,D, dont have any idea
about P. N is for performing any operation without lock for
example: read(n) means read without lock.
E is for error detection at operation level,
H is for half adjust for example 2+5.68=7.68 however with
the help of eval(h) a=2+5.68;value of a will be 7.7 and D
is use for date
