| This has been asked before on this forum. There's no command to find unwanted variables, although you can use the variable cross reference listing to find variables that are not used in the program. Whether or not they are wanted, of course, is a philosophical question.... |

Hi Robert ,
Can u tell what is that Variable cross reference listing
Do u mean just manually verifying ?
There is no other way apart from this
In Sysout .. We cant find anything specified that the variables that r not used ? |

If you specify XREF(FULL) as a COBOL compiler option, you will get a listing of every variable (among other things) in the program, where each is defined, and the PROCEDURE DIVISION lines that reference that variable. This is the compiler cross reference listing. If the variable is listed with no PROCEDURE DIVISION statements, then the variable is not used by that program. For example:
| Code: |
1PP 5655-G53 IBM Enterprise COBOL for z/OS 3.4.1 MF0094 Date 0
0An "M" preceding a data-name reference indicates that the data-name is modified
Defined Cross-reference of data names References
14 WS-COMP-1. . . . . . . . . . . 21
15 WS-COMP-2. . . . . . . . . . . 26
16 WS-COMP-3. . . . . . . . . . . 31
17 WS-DISP-1. . . . . . . . . . . 21 26 31
13 WS-VARIABLES |
shows WS-VARIABLES is not used but each of the other variables is used at least once.
And yes, I mean manually verifying -- there's tools that can tell you which variables aren't used but they are site specific and you would need to talk to your site support group, coworkers, or team leader to find out if such a tool is available at your site. |

Yeah, It should be shop specific.
It would be really grateful if you can share the source code of that command so that all of us can use the same ;-) |

APOSTSQL
ATTACH(TSO)
CCSID(37)
NOPADNTSTR
CONNECT(2)

| The compiler default is XREF(FULL) but it sometimes gets changed at sites concerned that the cross reference uses too much space. |

even i never use these option when compiling the program. But on listing i could see the defaults options (as mentioned above). By the way, at my shop we use Alchemist.
Thanks, |
