How can one generate Cobol COPYBOOKs for a CA Datacom/DB Table to see all of the fields and their PICTURE clauses.



There are 2 ways to do this: 

1 - One is to sign on to a CICS region and use transaction DDOL.

In DBMAINT mode, type the command "D TBL tablename STA PROD", hit enter, on the first line of that display, in the line commands, type DCB for “display copybook” on the TABLE row and hit PF4, and you will get a display like this:
========================== T O P ==================
           02  tablename
               03  GROUP-CODE        PICTURE X(2).  
               03  ANALYSIS-CODE    PICTURE X(2).  
               03  SHORT-DESC         PICTURE X(15). 
               03  LONG-DESC           PICTURE X(100).

Note: DCB is a margin command. For more other commands use the MARGIN command to display a list of the margin commands.

For more information see CA Datacom DataDictionary Online Reference Guide Chap "Margin Commands"

 2 - Second is by using DDUTILTY or DDICF  Batch programs:


//SYSPUNCH DD SYSOUT=*         PRINT OUTPUT                                     
//SNAPER   DD SYSOUT=A           CA-DATACOM/DB DUMPS                              
//SYSDUMP  DD SYSOUT=A         SYSTEM DUMPS                                   
//SYSIN    DD *                                                         
-USR DATACOM-INSTALL,NEWUSER                                            
-DEF PATH,STANDARD                                                     
-UTL LANGUAGE,COBOL                           
-UTL COPY,ELEMENT(ALL),PAY001                 

If you don't know the table’s Datadictionary name you can get that from a CXX report. In the example above I am pulling all elements in the table. If you have overlapping elements you may have to be more specific on what you want. The reason I started with elements is that most programs work on elements and not rows. 

Output looks like this:

-RPT START,TABLE,PAYROLL(PROD),STANDARD  ;                                             
-UTL COPY,ELEMENT(ALL),PAY001             ;                                             
-END                                                                 ;                                             
./ ADD NAME=PAY001                                                                                                    
           02  PAY-IDENTIFICATION.    <=== This is the first element (partial record)                                                                     
               03  PY-NUMBER                    PICTURE 9(5).                                                                      
               03  PY-ACTIVITY-CODE         PICTURE X(1).        
               03  PY-ACTIVITY-STATUS     PICTURE X(1).        
           02  PAY-FIGURES.                  <=== This is the second element (partial record)       
               03  FG-CURRENT-RATE        PICTURE 9(6)V9(2).   
               03  FG-YTD-WAGE                PICTURE 9(6)V9(2).   
               03  FG-YTD-COMMISSION  PICTURE 9(6)V9(2).   
               03  FG-YTD-TAX                    PICTURE 9(6)V9(2).   
           02  PAY-RECORD.                  <=== This is the whole record (If you look at the CXX report just look at the elements that start at offset 0 and cover the whole row).              
               03  RC-NUMBER                   PICTURE 9(5).                   
               03  RC-ACTIVITY-CODE        PICTURE X(1). 
               03  RC-ACTIVITY-STATUS    PICTURE X(1).                   
               03  RC-CURRENT-RATE       PICTURE 9(6)V9(2).              
               03  RC-YTD-WAGE               PICTURE 9(6)V9(2).              
               03  RC-YTD-COMMISSION  PICTURE 9(6)V9(2).              
               03  RC-YTD-TAX                    PICTURE 9(6)V9(2).           
                             ===>  Pick the elements used by your program.

For just a layout of the table/row use the control cards below:

Output looks like this:
./ ADD NAME=PAY001                                                 
           02  PAYROLL.                                            
               03  NUMBER                  PICTURE 9(5).                   
               03  ACTIVITY-CODE       PICTURE X(1).                   
               03  ACTIVITY-STATUS    PICTURE X(1).                   
               03  CURRENT-RATE        PICTURE 9(6)V9(2).              
               03  YTD-WAGES              PICTURE 9(6)V9(2).              
               03  YTD-COMMISSION   PICTURE 9(6)V9(2).              
               03  YTD-TAX                     PICTURE 9(6)V9(2).
