In comp-3 format sign is stoted in the last nibble along
with data for e.g +1234 last digit is +4 it comes as D

Answer / blessy

it is stored as hex value in the last nibble(4 bits) of the
storage. for eg: if the number is +100, it stores hex 0C in
the last byte. as 2D if the number is -102 .

Answer / srinivas adilapuram

The sign is stored seperately as rightmost half-a-byte
regardless of whether 'S' is specified in the PIC clause or not.

Hi,

suppose s9(3)v9(4) comp 3 is the data type then
3+4 = 7 half bytes will be used for data.
the last half byte will be used for sign

in this example number of digits is odd(7).
so total size occupied will be 7/2 + 1/2 =4 bytes

first seven half bytes from left will have data part. so the
right most half byte will have sign value.
if this right most half byte value is D (1101) then it is -ve
if it is C (1100) or F (1111) then it is considered as +ve.

example 2
S9(4)v(2) comp 3

here number of digits is even (4+2=6),so number of bytes
used will be 6/2 +1 =4 bytes.
in this example first half byte will be having 0000 value
this will be ignored while reading from data. the next six
half bytes will be having the six digits of data. and then
the last half byte will be having the sign value as said in
the example 1.

example 3
s9(4) comp3

4-even
first half byte no data(0000). next 4 half bytes data. the
last half byte will have sign value

Thanks
