COMP is a binary storage format while COMP-3 is packed
decimal format.
For comp-3 you can refer following examples -
Packed Decimal fields: Sign is stored as a hex value in
the last nibble (4 bits ) of the storage.
The actual number of bytes occupied in the file is about
half that. To calculate the number of bytes from the PIC,
add 1 (for the sign) to the total number of digits, divide
by 2, and round up if necessary. For example:
PIC S9(7) COMP-3. Byte size = (7 + 1) / 2 = 4
PIC S9(5)V99 COMP-3. Byte size = (5 + 2 + 1) / 2 = 4
PIC S9(6) COMP-3. Byte size = (6 + 1) / 2 = 3.5,
rounded to 4
Comp-3 fields reserve a nibble for the sign, even
for "unsigned" values, so the following fields are still 4
bytes:
PIC 9(7) COMP-3. Byte size = (7 + 1) / 2 = 4
PIC 9(6) COMP-3. Byte size = (6 + 1) / 2 = 3.5,
rounded to 4.
