Actually the formula is :-

if val(n) type p decimals 2 value 343.54. (here u must specify n value)

2n-1 is the total characters.

2 bytes will store a character / number

in the above case if u give n as 3,

it is interpreted as 2 * 3 - 1 = 5 characters.

3 bytes 34 - 1 byte , 35 - 2nd byte 4D - 3rd byte (D here is sign + or - ).

It means that soon we'll have another couple of guests, and your employer points total may reduce substantially - and they'll know it was down to you. Have a nice day.

Yes '3' stands for length. but in case of this data type no means for this length.

Only for character type value this has some means.

If you define as

DATA : P_VAL type c valur 'anil'.

WRITE:/ p_val.

then it will display only 'a' i'e only first character.

and if you write it as

DATA : P_VAL type c valur 'anil'.

WRITE:/ p_val.

now it will display anil.
