Hi Fayum,

Ignoring the remainder:

The # of bytes = ? / 2 + 1

For example: # of bytes in S9(5) = 5 / 2 = 2 remainder 1
= 2 +1
= 3

For example: # of bytes in S9(4) = 4 / 2 = 2 remainder 0
= 2 +1
= 3

What this tells us is to use an odd # of 9s in the PIC. It gives you more bang for the byte and its more efficient too.

HTH, Jack.

The answer for your ? is 18 in VS COBOL II*

COMP-3 CAN BE DEFINED AS 77 A PIC S9(18) COMP-3 BUT IT AGAIN DEPENDS UPON COMPILERS INSTALLATION

In addition to Macmillan, if you consider compiler option ARTITH then -
ARITH(compressed) - Default - Max length of numeric item is 18
ARITH(Extend) - Max length of numeric item is 32

Regards,
Sandip.
