Thanks

I Madhu, U CAN MOVE LOW-VALUE TO A COM-3 VARIABLE.
BELOW I SEND U AN EXAMPLE.
BYE BYE.
WORKING-STORAGE SECTION.
01 NUMA PIC 9(05) COMP-3 VALUE 3.
PROCEDURE DIVISION.
MOVE LOW-VALUE TO NUMA
ADD 1 TO NUMA
DISPLAY 'NUMA ' NUMA
MOVE 3 TO NUMA
DISPLAY 'NUMA ' NUMA
--------------------------------------------------------------------
RESULT:
NUMA 00001
NUMA 00003 |

hy madhugoodboy,
if you have a comp-3 unsigned,
just move zero to the variable.
if you look at the hex-value,
it is low-value...

yes..martin is spot on.
you can move low-values in comp3.
also for unsigned just move zeroes.

Madhu K,
In response to perez_a. At least under the Enterprise Cobol 3.1.0 you cannot move low-values to a comp-3 field, and I believe this is not possible under any IBM Cobol compiler.
perez_a, What compiler version are you running under?
| Code: |
005800 WORKING-STORAGE SECTION.
004515
002710 01 NUMA PIC 9(05) COMP-3 VALUE 3.
002800
015900 LINKAGE SECTION.

041400 PROCEDURE DIVISION.
033300
042110 MOVE LOW-VALUE TO NUMA
IGYPA3005-S "LOW-VALUE" AND "NUMA (PACKED INTEGER)" DID NOT FOLLOW THE "MOVE" STATEMENT COMPATIBILITY RULES. THE STATEMENT WAS DISCARDED.

042130 DISPLAY 'NUMA ' NUMA
042140 MOVE 3 TO NUMA
042150 DISPLAY 'NUMA ' NUMA
042130
MOVE 0 TO RETURN-CODE.

And, in response to martin9. Moving zero (0) to an unsigned comp-3 field does not result in vow-values. It results in an unsigned comp-3 value x?00000F?. The redefines below is in place so there is no data conversion during the ?DISPLAY?.
| Code: |

Result of running the above code.

One way to get low-values to a comp-3 field is to redefine it as above and move low values to the ?PIC X? field. But, this does not satisfy your question.
Another way is if the COMP-3 is defined as an elemental item, then you can move ?LOW-VALUES? to the group item (that is defined by default as ?PIC X?) example below
| Code: |
. 000019 005800 WORKING-STORAGE SECTION.
. 000020** 004515
. 000021** 002701 01 WS-GROUP1.
. 000022 002710 05 NUMA PIC 9(05) COMP-3 VALUE 3.
. 000023 002720 05 NUMX REDEFINES NUMA PIC X(3).

hy alll,
yeah i was not completely right,
i just forgot, that on an odd-length comp-3 field
the compiler will use one half-byte more to get an even-length
field. try it with pic 9(06) comp-3 or if you just use the initial
value of that field, which is low-values.
but it's very right, with redefining the comp-3
is probably the easiest way.... s.above

| Every comp-3 field in mainframe IBM COBOL has a sign nibble (4 bits), whether it's positive (C), negative (D) or unsigned (F) regardless of its length. |

Thanks all,
Now it has been confirmed that we can move the low values to comp-3 variable.
Regards
Madhu |

hy madhugoodboy,
but do not use it.
move some zeros as value, it's the better way
and you will be always on the sure side....
