Ditto?
Redefine it as a "U" file and display it with HEX ON? |

Anuj,
Check the DISPLAY operator of ICETOOL.
From the manual:
| Quote: |
DISPLAY also has two special ON fields you can use:
ON(VLEN) can be used for variable length record data sets to print the length of each record. |
Which is nothing but the contents of RDW.
RDW consists of 4 bytes out of which
first 2 bytes - Length of the record
3-4 bytes - Hexadecimal Zeroes

DITTO is a very old IBM utility program that was how many of us "hex-dumped" records, copied files, did rather dangerous disk "patching - DRL (disp record load) if i remember)" and many, many other things.
DITTO was/is an acronym for "Data Interfile Transfer, Testing, and Operations" Utility. |

Hi Dick,
I heard about DITTO in conjunction with VSAM, however never used it. I couldn't realized some/any connection of 'it' with RDW of VB files, Thanks. |

Hi Anuj,
DITTO is much older than vsam 
One of the DITTO commands was a "disk dump" that hex dumped physical blocks rather than logical records. This would let one see both the block descriptor as well as the record descriptor. |
