Help in removing last digits from sequential file.

Post by Bhaskar Virgo »

Hi,

I am in a new project. Over here only I am facing this problem. Many times, I found some sequential datasets have some number in the last 8 byte and don't get deleted even when in edit mode. Any proper way of removing them?

for fixed format datasets the last 8 bytes might be used for sequence numbering by ISPF.

before deleting them ask Your support why ( the sequence numbers ) are there

sequence numbers are seldom a problem,
unless by mistake somebody has renumbered an application dataset overwriting the last 8 bytes of each record.
cheers

so that I am sure that the information requested can be reached with a very small effort 8-)

I have used NUM ON, UNNUM followed by NUM OFF and it helped for this.

I have asked the support but they are not familiar with this behaviour. :(

Your support should be waware of the sequence numbers - they have been around since before TSO or ISPF. Try finding an old 80 column coding sheet, browse one online if need be, and look at the headings.
