| First of all you cant merge files with different record length. Second if you really want to merge those files you will have increase their length using file aid, copy by 3.3 option, select the 'T' in the screen then select the length (keep a flat length for all) AND then you need to initialize the extra fields. You can have blanks, zeros or spaces (I guess there are more options). After making the 3 files equal length you can simply merge them using sort utility. I guess yo know before merging you need to sort all the files. I hope this would help you. |
