Hi,
I am having a sequential file of LRECL=130. There are different columns in the files. How can I view only few columns. For Example Column1 (1-20), column2 (35-56) and column3 (100-125).

You cannot view few columns of a flat file. Use DFSORT for reformatting or extracting the required columns into another file. Sample JCL is as -

Code:
//sortin dd dsn=your.ipfile,disp=shr
//sortout dd dsn=your.opfile,disp=.......
//sysin dd *
   option copy
   outrec fields=(1,20,             * column 1
                        35,21,           * column 2
                        100,25)         * column 3
/*


The OP file contains only the required fileds

If you have FileAid it's fairly simple.

View the file "format"ed, that is, specify a copybook in the space provided.

After you bring up the file, enter "s n" (show names) on the cmd line. Note the numbers (shown to the left of the field names) of the fields you want to view, then enter (for example):

display only 1 2 9-13 72 108

The 9-13 references a range of fields beginning at field 9 and ending at 13.

It all depends, you can view the columns in a flat file if you have the Format option in your release.

eg do you have this in Veiw or Edit main screens?
Code:

  EDIT/VIEW parameters:                                                         
    Initial Macro  ===>            Confirm Cancel/Move/Replace     ===> N (Y, N)
    Profile Name   ===>            Action Bar in Edit/View         ===> Y (Y, N)
    Format  Name   ===>            Highlight coloring in Edit/View ===> Y (Y, N)
 Preserve VB record length  => N   Mixed Mode (NLS DBCS char. set) ===> N (Y, N)




the Format name has to be created in option 3.11 (if you have it)

Code:

                           Utility Selection Panel                             
Option ===>                                                                   
                                                                               
1  Library     Compress or print data set.  Print index listing.  Print,       
                 rename, delete, browse, edit or view members                 
2  Data Set    Allocate, rename, delete, catalog, uncatalog, or display       
                 information of an entire data set                             
3  Move/Copy   Move, or copy members or data sets                             
4  Dslist      Print or display (to process) list of data set names.           
                 Print or display VTOC information                             
5  Reset       Reset statistics for members of ISPF library                   
6  Hardcopy    Initiate hardcopy output                                       
7  Transfer    Download ISPF Client/Server or Transfer data set               
8  Outlist     Display, delete, or print held job output                       
9  Commands    Create/change an application command table                     
11 Format      Format definition for formatted data Edit/Browse               
12 SuperC      Compare data sets                             (Standard Dialog)
13 SuperCE     Compare data sets Extended                    (Extended Dialog)
14 Search-For  Search data sets for strings of data          (Standard Dialog)
15 Search-ForE Search data sets for strings of data Extended (Extended Dialog)

The above works, but is tedious, and is restricted to datasets small enough to edit/view.

If it switches you to browse mode, forget it.
