Hi,
I am working on a Easytrieve program. Here I will read one input field and based on my logic I want to update the same file.

In everywhere I see I can take the input file for input only. Is there anyway I can update the input file also?

If not how can I do this ?

Thanks a lot,
Robi

It doesn't look like it can be done against a SAM file. First off, why not just create a second file and rename after processing?
One way you might do what you want is for the first JOB to input the file to a virtual file and the second JOB read that virtual file and output it back to the original dsn - externally it will look like an update in place....
