Hi Friends,

In COMP-3 The SIGN is stored separately as the rightmost half-a-byte regardless of whether S is specified in the PICTURE or not.

The hexadecimal number C or F denotes a positive sign.

My question is ::

How it is decided whether to use hexadecimal number C or F

Example ::

77 I PIC 9(3) COMP-3 VALUE IS 374

the internal representation will be ::

0011 0111 0100 1111 i.e 374F

Is it possible like this ::

0011 0111 0100 1100 i.e 374C

Hope I am clear in my QUESTION.

Regards,
JITU
