Question related to KSDS

[malathy]

1) Is it possible to read a KSDS file without Key??

2) We have 100 records in a KSDS file. While reading some 51 st record some abend has occured. Again the file should not be read from beginning it should start reading from where it got abended??

By restarting, how do you get the key for 51 st record ??

Can someone help me in answering this question?

You can read a KSDS sequentially.

For number 2, what do you want to achieve by not starting from the first record?

reading some 51 st record

does this actually mean "reading the 51st record"?

not be read from beginning it should start reading from the first

What is the difference between read from the beginning, i.e. the first record, and reading from the "first" where "first" is presumably the "first record"?

Thanks for your Reply..Yes, I know that we can read KSDS file sequentially. But my query is whether it is possible to read KSDS file without key??

If you read the file sequentially, why do you need a key?

Malathy -

For your second query, you want to start reading X th record if the program previously abended in Xth record also you don't have any key?

If my assumption over your second query is correct - it is not possible to perform a DYNAMIC read in KSDS with-out key. if you don't pass key (assume initially the key variable is space) it will start reading the file >= space.

So it is programmer's responsibility to have some logic to hold the key value (say in table or other files) in order to do the above mentioned requirement on restart.

Hope this help.

Thanks.
