Hi,

I have a Flat File where we maintain a counter. I need to reset the counter to ZEROES if it is greater than 100. This is a daily job and I need to execute this using a JCL. Can anyone help?

Thanks
Arvind B

How do you identify the record that contains the counter? What is the starting position, length and format of the counter in that record?

It Starts at position 15, length is 3 and its a numeric. Maybe in the below format.

XXXX XXXXXXXX 100 XXXXXX XXXXX XXXXXXXXXXX

I want to read the file and re-write into the same file.
Maybe you can suggest the utility, I can refer and get the logic so that I learn better.

Thanks,

arvibala,

Using the same input as output can cause problems. Use the following JCL. we first copy the input to a temp dataset making changes and then copy it back to the original input
