Hi all,
Actually i have a COBOL code in a package and i was having some difficulty in Debugging that code, I wanted to get the whole flow of the program once the job starts its execution and calls the program (code). Its a real big code, so there was no way out except using DISPLAY statements wherever i thought i could find a track of the code and crack it  , fortunately i have found the solution for it, but i just wanted to know if there are any kind of an options in changeman where we can get an option for tracking out code during compiling it? I mean we might save time in putting down the DISPLAY statements after every para? |

Hi,
No, AFAIK, Changeman does not provide any such facility. I use a REXX, ADDISP, for this purpose, check if that works for you:
| Code: |
/* REXX */
/* */
/* Displays the paragraph names in a cobol pgm /
/* It works if the edit mode is NUM ON STD or NUM OFF */
/* */
/*TRACE ?I*/
ISREDIT MACRO
ADDRESS ISREDIT "F 'PROCEDURE DIVISION' 8 FIRST"
ADDRESS ISREDIT "F P'¬' 8"
DO UNTIL RC > 0
ADDRESS ISREDIT "(THELINE) = LINE .ZCSR"
IF POS("EXIT",THELINE) = 0 ,
& POS("*",THELINE) = 0 ,
& POS("-INC",THELINE) = 0 ,
& POS("COPY",THELINE) = 0
THEN
DO
PARSE VAR THELINE NUM " " LINE1 "." LINE2
LINE3 = STRIP(LINE1,'L'," ")
/* LINE3 = "FJGNL - "LINE3 */
ADDRESS ISREDIT "LINE_AFTER .ZCSR = ' DISPLAY '"LINE3"''"
END
ADDRESS ISREDIT "F P'¬' 8"
END |
First, try it on some "test-component". |

Hi,
At my shop we are not allowed to promote a code to production with those many DISPLAYs - you should delete them (unless they are allowed at your end in production) once you are done with debugging. Here is other REXX, which I use for deleting those DISPLAYs added with the above REXX:
| Code: |
/* REXX */
/* DELETES THE DISPLAY LINES ADDED BY ADDISP MACRO */
/*TRACE ?I*/
ISREDIT MACRO
ADDRESS ISREDIT "F 'PROCEDURE DIVISION' 8 FIRST"
ADDRESS ISREDIT "F P'¬' 8"
DO UNTIL RC > 0
ADDRESS ISREDIT "(THELINE) = LINE .ZCSR"
IF POS("EXIT",THELINE) = 0 ,
& POS("*",THELINE) = 0 ,
& POS("-INC",THELINE) = 0
THEN
DO
ADDRESS ISREDIT "(CURLINE,CURCOLM) = CURSOR"
CURLINE = CURLINE + 1
ADDRESS ISREDIT "CURSOR = " CURLINE CURCOLM
ADDRESS ISREDIT "(DISLINE) = LINE .ZCSR"
IF POS("DISPLAY",DISLINE) <> 0 ,
THEN
DO
ADDRESS ISREDIT "(HERE) = CURSOR"
ADDRESS ISREDIT "LABEL " HERE " = .CURRENT"
ADDRESS ISREDIT "DELETE .CURRENT"
END
END
ADDRESS ISREDIT "F P'¬' 8"
END |

if you have no debuggers in your shop,
use:
SOURCE COMPUTER WITH DEBUG.
column 7 D (and code a display in the line.)
will compile the code to include those lines with D in 7
after you have finished debugging, instead of deleting all the display lines
change SOURCE COMPUTER WITH DEBUG.
to SOURCE COMPUTER. |

See the Language Reference manual for the correct syntax of the SOURCE-COMPUTER paragraph. The way I code this is:
| Code: |
*UNCOMMENT THE FOLLOWING LINE TO ENABLE DEBUGGING MODE
*SOURCE-COMPUTER. IBM-ZOS WITH DEBUGGING MODE. |
This allows me to enable/disable debugging mode very easily. |

Suggest both you (and the rest of the forum) will be better served if you ask technical questions in the proper part of the forum rather than via PM.
Some considerations are that if a question is sent via PM, there may be an extended amount of time before the question is even seen. Another is that if some question/answer dialog goes on between only 2 people, others cannot offer help or use the information presented in the PMs.
PM should be used for "Private Messages" - not technical discussion. If someone has a question, it is almost certain that someone else has the same question and will benefit from the discussion.

Hi All,
I have found the Error, I have just initialized the Variable as like below,
| Code: |
CURLINE = 0
ADDRESS ISREDIT "(CURLINE,CURCOLM) = CURSOR"
CURLINE = CURLINE + 1 |
Now the REXX code is working fine..
Thanks Anuj.. |

If you are new to REXX I would suggest you to read the forum manuals and then search the REXX forum as to how to run a simple REXX code.
One such post of mine for executing a REXX code.
RUN A REXX |

Thanks Aaru & Anuj for your response.
Last week, I added the displays in all paragraphs and sections in my cobol program. In my shop, we have a CLIST code which will add displays in all para and sections.
I know, how to run Rexx code only basic level (Only Basic level - like EX command in front of the member name or TSO EXEC "PDS(MEMBER)").
I just asked, how to run the above code? (which means, where do I need to include my cobol program?) |

There is a link to manuals at the top of the page. If you click it, find the COBOL Language Reference, and search you can find
| Quote: |
APPENDIX1.4.1 Debugging lines
A debugging line is a statement that is compiled only when the compile-time switch is activated. Debugging lines allow you, for example, to check the value of a data item at certain points in a procedure.
To specify a debugging line in your program, code a D in column 7 (the indicator area). You can include successive debugging lines, but each must have a D in column 7. You cannot break character-strings across two lines.
All your debugging lines must be written so that the program is syntactically correct, whether the debugging lines are compiled or treated as comments.
You can code debugging lines anywhere in your program after the OBJECT-COMPUTER paragraph.
A debugging line that contains only spaces in Area A and in Area B is treated as a blank line. |
