I have below code.
| Code: |
ID DIVISION.
PROGRAM-ID. RENAMPGM.
ENVIRONMENT DIVISION.
DATA DIVISION.
WORKING-STORAGE SECTION.
01 GRP.
02 A.
03 X PIC 999.
03 X1 REDEFINES X PIC X.
03 B.
04 Y PIC X VALUE 'B'.
04 Y1 PIC X(10) VALUE ALL 'B1'.
04 Y2 PIC X(10) VALUE ALL 'B2'.
03 C VALUE 'A SDFL 4087'.
04 Z PIC X.
04 Z1 PIC X(5).
04 Z2 PIC X(5).
66 RNM3 RENAMES X1 THRU Z1.
PROCEDURE DIVISION.
MAIN-PARA.
MOVE 11 TO X.
DISPLAY RNM3.
STOP RUN. |
Per my knowledge the answer (RNM3 value) should be
1BB1B1B1B1B1B2B2B2B2B2A SDFL, But system gave answer like
11BB1B1B1B1B1B2B2B2B2B2A SDFL
Could you please explain the reason |

just watching the first value... 'for me' none of them is right.
if x = 11 (011) the value of x1 is 0. |

Ravi kumar Siluveru ,
not being in the habit of exploiting enteprise cobol's abilitiy to make illogical redefines,
don't know how it will map.
but, suggest you look at the map to determine how address assignment was done.
Ravi,
why don't you supply us with the map of these data definitions,
then we will all know without having to burn-up our machines to determine the answer. |

Dick,
Sorry, I am not getting 'Map of the data definitions'. My intention is to know if we rename the redefined item, will rename work or not?
will it take the original item (here X) instead of redefined item (X1)? |

address of X1 = Address of X
| Code: |
offset
00 01 GRP.
00 02 A.
00 03 X PIC 99.
00 03 X1 REDEFINES X PIC X.
02 03 B.
02 04 Y PIC X VALUE 'B'.
03 04 Y1 PIC X(10) VALUE ALL 'B1'.
13 04 Y2 PIC X(10) VALUE ALL 'B2'.
23 03 C VALUE 'A SDFL 4087'.
23 04 Z PIC X.
24 04 Z1 PIC X(5).
29 04 Z2 PIC X(5).
0 66 RNM3 RENAMES X1 THRU Z1. |
thus rnm3 goes from offset 0 to 28 |

The storage map can be very useful and it's easy to add the compile option to get it. The map for your code is:
| Code: |
Source Hierarchy and Base Hex-Displacement Asmblr Data Data Def
LineID Data Name Locator Blk Structure Definition Data Type Attributes
2 PROGRAM-ID MF0154------------------------------------------------------------------------------------------------------*
15 1 GRP . . . . . . . . . . . . . . . . . . . . . BLW=00000 000 DS 0CL35 Group
16 2 A . . . . . . . . . . . . . . . . . . . . . BLW=00000 000 0 000 000 DS 0CL35 Group
17 3 X . . . . . . . . . . . . . . . . . . . . BLW=00000 000 0 000 000 DS 3C Disp-Num

If you study it, you will learn everything you need to know about why you got the results you got. |

well that is your answer.
X1 redefines X means starting address of both is the same, regardless of length.
the earlier 999 had me confused, (actually I want to call you a liar)
but as 99, then it makes sense.
as guyc showed in his post. |
